Sarcoidosis is a multi-system granulomatous disorder of an unknown etiology and affects individuals worldwide. It is characterized pathologically by the presence of non-caseating granulomas in more than one involved organ. However, pleural involvement of sarcoidosis is rare and there are no reported cases in Korea. Traditionally, sarcoidosis has often been treated with systemic corticosteroids or cytotoxic agents. In particular, chylothorax with sarcoidosis is usually treated with corticosteroid for approximately 3~6 months, followed by repeated therapeutic thoracentesis, talc pleurodesis, dietary treatment, or thoracic duct ligation where needed. We encountered a 46 years old female patient presenting with cough, dyspnea and both hilar lymphadenopathy (stage I) on chest radiograph. The patient was diagnosed with a non-caseating granuloma, sarcoidosis by a mediastinoscopic biopsy. For one month, she had suffered from dyspnea due to right side pleural effusion, which was clearly identified as a chylothorax on thoracentesis. Corticosteroid therapy with dietary adjustment was ineffective. She was treated successfully with a subcutaneous injection of octreotide for 3 weeks and oral corticosteroid. We report a case of successful and rapid treatment of chylothorax associated with sarcoidosis using octreotide and oral corticosteroid.

These studies were carried out to investigate the effects of liver-fluke infection on the reproductive disorder and milk and meat production in Korean Native Goat. A survey of infected goat in Chungnam district was conducted with 474 head by interdermal reaction and also a clinical observation was founded. A experiment was carried out to determine the effects of liver fluke extract on the reproductive disorder by subcutaneous injection and milk and meat yield were measured from treat ed goats. The results obtained were summarized as follows. 1. The rate of positive goat was 71.3% among the surveyed goat and the highest rate was appeared at 3~4 years old goats as 81.4%. 2. The treated goats lost condition and failed to thrive, and became progressive weaker. 3. In hemogram, observation, the rate of eosinophil leucocyte was increased significantly by extract treated. 4. It was appeared the pathogenic signs such symptoms poisoning liver function disturbance and reproductive disorder from treated goats with liver fluke extract. 5. In milking goat the milk yield droped significantly and fattening goat did not fatten. 6. The gross income value per capita was lower from infected goat and it was analysed more sensitivly in net income value.
Purpose: Adipose-derived stromal cells (ASCs) are readily harvested from lipoaspirated tissue or subcutaneous adipose tissue fragments. The stromal vascular fraction (SVF) is a heterogeneous set of cell populations that surround and support adipose tissue, which includes the stromal cells, ASCs, that have the ability to differentiate into cells of several lineages and contains cells from the microvasculature. The mechanisms that drive the ASCs into the osteoblast lineage are still not clear, but the process has been more extensively studied in bone marrow stromal cells. The purpose of this study was to investigate the osteogenic capacity of adipose derived SVF cells and evaluate bone formation following implantation of SVF cells into the bone defect of human phalanx. Methods: Case 1 a 43-year-old male was wounded while using a press machine. After first operation, segmental bone defects of the left 3rd and 4th middle phalanx occurred. At first we injected the SVF cells combined with demineralized bone matrix (DBM) to defected 4th middle phalangeal bone lesion. We used P (L/DL)LA [Poly (70L-lactide-co-30DL-lactide) Co Polymer P (L/DL)LA] as a scaffold. Next, we implanted the SVF cells combined with DBM to repair left 3rd middle phalangeal bone defect in sequence. Case 2 was a 25-year-old man with crushing hand injury. Three months after the previous surgery, we implanted the SVF cells combined with DBM to restore right 3rd middle phalangeal bone defect by syringe injection. Radiographic images were taken at follow-up hospital visits and evaluated radiographically by means of computerized analysis of digital images. Results: The phalangeal bone defect was treated with autologous SVF cells isolated and applied in a single operative procedure in combination with DBM. The SVF cells were supported in place with mechanical fixation with a resorbable macroporous sheets acting as a soft tissue barrier. The radiographic appearance of the defect revealed a restoration to average bone density and stable position of pharyngeal bone. Densitometric evaluations for digital X-ray revealed improved bone densities in two cases with pharyngeal bone defects, that is, 65.2% for 4th finger of the case 1, 60.5% for 3rd finger of the case 1 and 60.1% for the case 2. Conclusion: This study demonstrated that adipose derived stromal vascular fraction cells have osteogenic potential in two clinical case studies. Thus, these reports show that cells from the SVF cells have potential in many areas of clinical cell therapy and regenerative medicine, albeit a lot of work is yet to be done.
The effects of faecally excreted ivermectin on the survival and growth of the common Korea earthworm Eisenia fetida (Savigny), have been studied in the laboratory. Cow dung was collected 1, 2, 3 and 7 days after ivermectin subcutaneous injection. The mortality of the worms provided with untreated dung was 0% whereas mortality within a week was high as 73.7%, 98.3% in dung which were excreted 1 and 2 days from dosing, respectively. The growth rate of the worms fed dung from 1 day excreted dung from cattle given ivermectin was 75% lower than that recorded on the control. In total number of hatchling earthworm in each treatment, 1 day after treatment produced the lowest compared with untreated control. However, dung from cattle treated with ivermectin did not prevented the rate of hatchling from each cocoon of earthworm. The results show that ivermectin is less toxic to $2^{nd}$ generation of earthworm. We concluded that ivermectin have adverse effects on the survival and growth of E. fetida when exposed through dung under laboratory conditions. This results will be discussed in relation to the effects of anthelmintics on non-target organism in our ecosystem.
Tetanus is an acute, often fatal, and infectious disease of all species of domestic animals caused by the neurotoxin of Clostridium tetani (C. tetani). This disease is usually known to develop after microbial contamination in the deep or penetrating wound sites. In February 2017, a farmer who was raising 76 cows injected foot and mouth disease vaccine to three or more cows with one syringe. Their clinical symptoms were observed 2 to 16 days after the vaccination. The initial symptoms were stiffness, rigidity of the neck and limbs, pricked ears, and prolapse of the third eyelid. Subsequently, there was recumbency with extension of the limbs, convulsions and opistotonus and the affected 20 cows were all died. Two dead cows were submitted to Animal and Plant Quarantine Agency for disease diagnosis. At necropsy, a focal edematous abscess of 15 to 20 cm in diameter was grossly observed in the subcutaneous and intramuscular tissue of scapular region and filled with a large amount of greenish pus. The feed was full in oral cavity and slightly observed in the trachea and lobes of lung. Histopathologically, focal granulomatous nodules with eosinophilic materials in the tissue were observed. In the lung, aspiration pneumonia and gram (+) bacteria were seen. The C. tetani was isolated in samples anaerobically cultured using reinforced clostridial medium and identified by PCR. To our knowledge, no previous outbreak of tetanus in cattle has affected such a high number of animals; neither has it been associated with misuse of the same syringe and needle to administer multiple individuals.

Objectives : The purpose of this study was to investigate the anti-inflammatory effect of Goihwa-san water extract(GHS) in vitro & in vivo. Methods : In vitro, we evaluated the anti-inflammatory effect of GHS by comparing the Raw 264.7 cells with 10, 30, 100, 300㎍/㎖ of GHS for 1 hour before Lipopolysaccharide(LPS) to the single LPS treated group. We examined the relative cell viability by MTT assay and the relative level of LPS, Loxoribine(LOX), Peptidoglycan(PGN), Flagellin(FLA)-induced NO production by using Griess reagent and measured relative iNOS protein level and COX-2 protein level by using western blot and Image analyzing system. We measured the production of TNF-α, IL-1β, and IL-6 by each ELISA kits and then measured the relative levels of IκBα, p-IκBα in whole-cell lysate fraction and NF-κB in nuclear fraction by using western blot and Image analyzing system. In vivo, we induced the paw edema by subcutaneous injection of 100㎕/rat CA and measured the swelling volume of paw by using a plethysmometer and then measured the relative iNOS protein level by using western blot. Results : As a result, in vitro, LPS, PGN-induced NO production was significantly inhibited by pretreatment with GHS. GHS reduced LPS, PGN-induced iNOS expression, PGN-induced COX-2 expression and LPS-induced production of cytokine(TNF-α, IL-1β, IL-6). Expression of IκBα was increased by pretreatment with GHS 100㎍/㎖. And the expression of p-IκBα and NF-κB were decreased by pretreatment with GHS 100㎍/㎖. In vivo, CA-induced inflammation rat model was used for the evaluation of the anti-inflammatory effect of GHS. 0.3 or 1.0g/kg of GHS significantly reduced the increases of paw swelling and iNOS expression in paw tissues. Conclusions : These results show that GHS can decrease inflammatory response via inhibition of the NF-κB pathway in vitro. And in vivo, the anti-inflammatory effect suggest the clinical basis of GHS for the treatment of inflammatory diseases.
It is well known that diabetes mellitus is associated with metabolic derangements, such as hyper-glycemia, ketosis, glycosuria, and also widespread alterations in the blood vessels, kidneys, eyes, peripheral nerves and heart. It is also recognized that healing of skin wound is delayed in diabetics. In bone, according to Aegerter, osteopenia develops in diabetes mellitus and it is chiefly ascribed to overutilization of protein. Shim claims that total blood flow to the entire skeletal system is approximately 4 to 8 percent of resting cardiac output and blood supply to the skeletal system would be decreased on account of secondary arteriosclerotic changes in the diabetics. An adequate blood supply is an essential factor in the healing process of fracture, and disturbed blood flow, either local or systemic, will invariably delay union of the fragments or the fragments from being fused. As the author has encountered several cases of diabetics in whom healing of fracture was delayed or incomplete, this experimental study was undertaken to elucidate the effects of hyperglycemia and diabetes mellitus on the healing process of fracture. In this experiment adult albino rabbits, weighing about 2 kg. were used and divided into 6 groups. The femur of each animal was fractured surgically, and then the healing process of fracture was periodically checked by radiography at an interval of one week for a period of 6 weeks. Thereafter, all the rabbits were killed to obtain tissue preparation of the femur. The experimental groups were as follows; 1) Control group: Six rabbits sustained a surgical fracture to the femur, without being given any other treatment or drug. 2) Alloxan-treated group: For inducing diabetes, alloxan was given intravenously to 17 rabbits in various dose as follows; to 7 of them 40 mg/kg, to 6 rabbits 80 mg/kg and to 4 rabbits 120 mg/kg of body weight, respectively. 3) Insulin-treated group: Protamine-zinc insulin was injected subcutaneously to each of 6 rabbits in a daily dose of 1 unit per kilogram of body weight. 4) Group treated with insulin after alloxan: Four rabbits were given 80 mg of alloxan once and than 1 unit of insulin per kilogram of body weight daily. Another 5 rabbits were injected 1 unit of insulin per kg of body weight daily following administration of alloxan in a dose of 120 mg/kg. 5) Homotransplantation group: Following intravenous injection of alloxan in a dose of 120 mg/kg, 10 rabbits underwent homotransplantation of a short bone segment to the femur. Five of them were subsequently given 1 unit/kg of insulin daily. 6) Sugar-treated group: six rabbits were fed $15{\sim}20$ gm of sugar daily throughout the period of experiment. The results obtained are summarized as follows; 1. Blood sugar level and damage to the pancreatic islet increased proportionately when alloxan was given to the rabbits in various doses. No appreciable change could be observed in the islets when the blood sugar level was altered by either oral administration of sugar or subcutaneous injection of insulin. 2. Comparing with the control group, healing of fracture was delayed in the alloxan-treated group, while callus formation and periosteal reaction were shown to be more prominent in this group and subsequently, the ultimate osseous tissue formed at the fracture site was significantly smaller in amount and less compact. These findings were more marked as the amount of alloxan increased. 3. Administration of insulin prevented the delay in healing process of fracture in the rabbits with alloxan-induced hyperglycemia. In this case, the course and progression of fracture healing were almost similar to those of control group. 4. Union between the host bone and the fragment transplanted from other rabbit of the same species was more delayed in the group treated with alloxan alone than in the group to which insulin was administered after development of alloxan-induced diabetes. In both groups periosteal new bone developed from the ends of the host bone, above and below the transplanted fragment, and directly fused with failure of periosteal callus to bridge the adjacent ends of the host bone and the transplanted fragment. 5. The healing process of fracture was not inhibited by alteration in blood sugar level when the blood sugar was abnormally increased by excessive sugar intake or lowered by administration of insulin alone. The healing of fracture in these groups progressed similarly as in the control group. In brief summary, it appears that the healing process of fracture would be definitely disturbed in diabetic state brought about by damage to the pancreatic islet. As such an inhibition could be overcome with insulin, it seems that insulin plays an important role in healing of fracture, but alteration in blood sugar level alone does not modify healing process of fracture to significant degree.

Uncooked powered diet (Saengshik) composed of grains, vegetables, mushrooms and fruits have various physiological functions including strong antioxidant and potent anticancer effects by many kinds of bioactive phytochemicals. The objective of present study was to identify the anticancer effects of vitamin C and saengshik on colon cancer induced by CT-26 cell line in BALB/c mice. As the result, the tumor volumes of vitamin C-mixed diet group (VC) showed no significant differences compared with control group (C) after subcutaneous injection of CT-26 cell lines. However saengshik group (S) showed a significant effect, inhibiting the growth of cancer by 56.2% ($4.8{\pm}9.0\;mm^3$), 48.1% ($80.8{\pm}60.0\;mm^3$), 43.2% ($135.2{\pm}117.2\;mm^3$), 55.5% ($233.6{\pm}248.2\;mm^3$), 69.2% ($304.6{\pm}442.5\;mm^3$) and 70.7% ($464.9{\pm}705.9\;mm^3$) respectively as compared with C group at an interval of 5 days after injection of the CT-26 cells into mice. Also the final tumor volume of S group exerted a significant differences as compared with one of C group (p<0.05). Especially in the case of S group (n=10), the tumors in 2 of 10 mice entirely disappeared at 25th day. Our results suggest that saengshik possess a strong inhibitory action against tumor growth induced by CT-26 colon cancer cell line in the mice. Further studies of saengshik are required to confirm the cancer prevention effect and possibility of adjuvant cancer therapy.
Fischer 344 rats aged six weeks were diYided into four groups and group 1, 2, and 3 of rats were given an intraperitoneal injection of diethylnitrosamine at 200 mg/kg body weight and group 4 was given saline alone. Two weeks after beginning of the experiment, group 1 and 2 of rats were begun to feed on diets containing 0.02% 2-acetylaminofluorene as a promoter for four weeks. Three weeks after beginning of the experiment, all groups were performed partial hepatectomy. During the last two weeks, group 1 and 3 of rats were received subcutaneously 3 consecutive weekly doses of iron dextran at 0.125 ml/100 g body weight. Subcutaneous injection of iron dextran resulted in hepatic siderosis in group 1 and 3 of rats. Pre neoplastic nodules were identified histopathologically by two markers, resistance to exogenous iron accumulation and glutathione S-transeferase placental form (GST-P) activity, while early carcinogen induced foci were hardly resistant to iron accumulation and though a few lesions were identified, it could hardly be distincted from normal hepatocytes of surroundings. However, GST-P positive nodules as well as foci were clearly distincted from normal hepatic cells of surroundings. In the quantitative analysis of carcinogen-induced nodules and foci, more lesions were detected by immunohistochemical method for GST-P than by prussian blue staining for resistant to iron accumulation. It is concluded that immunohistochemical marker for GST-P is more sensitive and reliable than iron-resistance marker, and that iron-resistance is not useful marker for early detection of carcinogen-induced hepatic lesions.
It was previously reported that red ginseng extract inhibited carcinogenesis by urethan, DMBA and aflatoxin $B_1E (Cancer Detection and Prevention, 6: 515-525, 1983). In an attempt to investigate the mechanism of the anticarcinogenic effect of ginseng, we assayed natural killer (N.K) activity in mice treated with urethan and benzo(a)pyrene. In our experiment newly born Swiss Webster mice, less than 24 hrs. old, were given a single subcutaneous injection of lmg of ure-than and 40ug of benzo(a)pyrene. The mice had been administered with ginseng since weaning, and sacrificed at various intervals. Major organs were examined both, with the naked eye and microscopically. N.K. activity of spleen cells was analyzed in a 12-hour $^{51}Cr^-release$ assay against YAC-1 cells. Administration of ginseng resulted in an increase of N.K. activity by $18\%$ at 4 weeks, $20\%$ (P < 0.05) at 6, $29\%$ (P < 0.05) at 12, and $13\%$ at 24 following a single injection of urethan. At the same time, significantly lower incidences of lung adenoma were noted at 6 weeks $(50\%)$ and 12 weeks $(27\%)$ following the administration of ginseng to urethan-injected mice. This result indicates that the enhancement of N.K. activity by ginseng makes a contribution to its anticarcinogenic effect. On the hand, N.K. activity was suppressed by benzo(a)pyrene during the time span of this experiment and it almost returned to the level of controls following the adminsitration of ginseng. However, the lung adenoma induced by benzo(a)pyrene began to occur at 48 weeks in which N.K. activity had naturally declined to a very low level in all experimental mice, and administration of ginseng did not decrease the incidence. In explanation of this result, we might propose that the recovery of the N.K. activity by ginseng had little effect on the incidence of lung adenoma because of the long latent period of carcinogenesis by benzo(a)pyrene. In conclusion, these results suggest that the anticarcinogenic effect of ginseng in urethan-treated mice may be related to the augmentation of N.K. activity.
