Background: Among the respiratory diseases, there are a lot of cases of pleural effusion. The most common cause is tuberculosis. But the other cause such as lung malignancy is in an increasing tendency because of the development of diagnostic procedure, the decrease of the prevalence of the tuberculosis and the increase of the longevity. We need to know the accurate diagnosis as soon as possible for the correct therapy. Method: A clinical observation was made on 315 cases of pleural effusion seen at Pusan Adventist Hospital, from Jan, 1989 to Dec, 1992. For diagnostic procedure, thoracentesis, lymph node biopsy, bronchoscopy and percutaneous biopsy of the parietal pleura with Cope needle were performed. The following are parameters used in seperating the exudate from the transudate: pleural protein 3.0 g/dl, pleural protein/serum protein ratio 0.5, pleural LDH 200 IU, pleural LDH/serum LDH ratio 0.6, pleural cholesterol 60 mg/dl and pleural cholesterol/serum cholesterol ratio 0.3. Each parameters were compared, and misclassified rate and diagnostic efficiency were calculated. Results: The most common cause of exudate pleurisy was tuberculosis (82.3%) and malignancy was next (12.2%). The chief complaints of pleural effusion were noted as dyspnea (58.7%), chest pain (54.9%), coughing (50.2%) and fever (36.2%). Location of pleural effusion was noted as right side (51.4%), left side (41.3%) and both sides (7.3%). Amount of pleural effusion of the chest X-ray was minimum (46.8%), moderate (40.5%) and maximum (12.7%). Misclassified rates for each parameters in seperating the exudates from the transudates were as follows; protein: 5.2%, pleural protein/serum protein:7.6%, LDH: 13.9%, pleural LDH/serum LDH: 6.9%, cholesterol: 8.0%, pleural cholesterol/serum cholesterol: 5.6%. On the pleural biopsy, the tuberculosis granuloma was 60.8%, malignancy was 13.6%, infection was 2.3% and nonspecific inflammatory reaction was 23.3%. Conclusion: on the basis of the above results, the most common cause of exudative pleurisy was tuberculosis. We think that the plerual cholesterol/serum cholesterol ratio is the most useful supportive parameter in separating the exudates from the transudates. For accurate diagnosis, the pleural biopsy is the first procedure and repeated pleural biopsy of nonspedcific inflammatory reaction is required.

Most cancer patients are treated with surgery, chemotherapy or radiation as anticancer therapies. Especially in the case of radiation, these treatments produce adverse effects such as vomiting, weight loss, anorexia, normal cell damage and malabsorption. The major goal of this study was to determine the effect of irradiation on the nutritional and immune status in irradiated rats. A secondary goal was to determine the effectiveness of high protein diet (HP) and resveratrol (Res) in minimizing the adverse effects of radiation. Rats were divided into four groups: normal diet (NP), HP, NP + Res and HP + Res groups. Each group was further divided into subgroups that received radiation (RT group) and one that did not (non-RT group). Each diet was supplied from $12^{th}$ day prior to irradiation treatment with irradiation dose of 17.5 Gy. The diets were continued until 10th day after radiation treatment and animals were sacrificed. The radiation treatment showed decreased body weight, serum protein and HDL levels and increased TG and LDL levels in nutritional status. HP, NP + Res and HP + Res groups reduced the level of serum LDL and TG in irradiated rats. NP + Res and HP + Res groups increased reduced albumin level of serum in RT group. In case of immune status, the radiation treat-ment showed decreased WBC, lymphocytes and increased neutrophil and eosinophil levels. The levels of serum IL-2 and IL-6 were significantly increased by radiation, however the cytokine levels decreased in all dietary treatment groups. These results showed that high protein diet and resveratrol supplementation seem to minimize the adverse effects of radiation on lipid nutritional status and inflammation response in the rat model.
The common word flavonoids is often used to classify a family of natural compounds, highly abundant in all higher plants, that have received significant therapeutic interest in recent years. Naringin is associated with a reduced risk of heart disease, neurodegenerative disease, cancer and other chronic diseases; however the molecular basis of this effect remains to be elucidated. Thus we attempted to elucidate the anti-allergic effect of Naringin in ovalbumin (OVA)-induced asthma model mice. The OVA-induced mice showed allergic reactions in the airways. These included an increase in the number of eosinophils in bronchoalveolar lavage (BAL) fluid, an increase in inflammatory cell infiltration into the lung around blood vessels and airways, airway luminal narrowing, and the development of airway hyper-responsiveness (AHR). The administration of Naringin before the last airway OVA challenge resulted in a significant inhibition of all asthmatic reactions. Accordingly, this study may provide evidence that Naringin plays a critical role in the amelioration of the pathogenetic process of asthma in mice. These findings provide new insight into the immunopharmacological role of Naringin in terms of its effects on asthma in mice.
The degree of hearing impairment of chronic otitis media will indicate the nature and severity of middle ear pathology especially condition of ossicular chain, size of ear drum perforation and location of granulation tissue in the middle ear cavity. The subjects were 189 ears of tympanoplasty for chronic otitis media and divided into four groups as follows: Normal ossicular chain with only ear drum perforation (group I), normal ossicular chain with granulation tissue only around the ossicles regardless of any other region (group II), ossicular ankylosis or fixation of handle of malleus to promontory with or without granulation tissue around the ossicle (group III) and ossicular interruption by partial or complete destruction(groupf IV). The results were concluded as follows: 1) The average hearing threshold of chronic otitis media was 44.6 dB and hearing threshold was closely related to the condition of ossicular chain. Hearing threshold became greater in order of normal ossicular chain, ankylosis and interruption. 2) The average hearing threshold of ossicular interrupted group was 49.1 dB and it was greater in the cases of total destruction than that of partial destruction. 3) The hearing loss in the cases of normal ossicular chain with only tympanic membrane perforation was within 45 dB and this level was presumed to represent normal ossicular function. The degree of hearing loss was in proportion to the size of ear drum perforation and when over 45 dB, other middle ear pathology was suggested. 4) In the cases of small ear drum perforation with normal ossicular function, the hearing threshold was within 30 dB. 5) In the type of audiogram, flat type was 30.2% and ascending type 35.4%. Descending type was more frequent in the cases of normal ossicular mobility with granulation tissue around the ossicle and flat type was observed frequently in the cases of ossicular ankylosis. 6) Carhart's notch was seen in 14 cases (7.4%) and observed mainly in ossicular ankylosis. 7) There was no relation between hearing threshold and histopathological type of granulation tissue in chronic otitis media. However the degree of hearing impairment was related to the location of granulation tissue in the middle ear cavity. 8) Authors recognized the granulation tissue compensated the function of interrupted ossicular chain.
Background and Object : Immunostimulatory CpG-oligodeoxynucleotides (ISS CpG-ODN) up-regulate the $T_{H1}$-type immune response and down-regulate the $T_{H2}$-type response. This study was performed to investigate the immune response changes resulting from ISS CpG-ODN on bronchial hyperresponsiveness, eosinophilic inflammation and mucus hypersecretion in rat asthma. Materials and Methods : 10 normal controls(NC) and 26 asthmatic rats, which were generated by ovalbumin(OVA) sensitization and challenge, were studied. The asthmatic rats were randomized into 11 asthma controls(AC) and 15 in the asthma-CpG treatment group(CpG). The CpG group was administered ISS CpG-ODN intramuscularly and the AC group was administered a placebo(0.9% NaCl) on day 15 and 20. After CpG-ODN or placebo administration, we measured the IFN-${\gamma}$($T_{H1}$-type cytokine) and IL-4($T_{H2}$-type cytokine) levels in the bronchoalveolar lavage fluid(BALF), the specific airway resistance(sRaw), eosinophilic fraction in BALF, eosinophilic infiltration, goblet cell dysplasia and MUC5AC gene expression in the lung tissue. Results : In the BALF of the CpG group, the IFN-${\gamma}$ concentration was significantly high and the IL-4 concentration was significantly low when compared with the AC group. Both the sRaw and eosinophilic fraction, and infiltration into the BALF and lung tissue significantly lower in the CpG group when compared with the AC group. However, little difference in goblet cell dysplasia and MUC5AC gene expression was observed between the CpG group and the AC group. Conclusion : ISS CpG-ODN decreases bronchial hyperresponsiveness and eosinophilic inflammation in the rat asthma model through the up-regulation of the $T_{H1}$-type immune response with the down-regulation of the $T_{H2}$-type response. However, the effect of these immune response changes on mucus hypersecretion was is not remarkable in this study.
Cornus officinalis Siebold & Zucc. is traditionally used as an edible and medicinal plant in many countries in East Asia. Previous studies have shown the pharmacological potential of extracts and components of C. officinalis, but comparative analysis of the composition of the leaf, stem, and fruit extracts has been insufficient to date. In the present study, the content of active antioxidant and anti-inflammatory ingredients was verified in different C. officinalis parts (under-ripe sansuyu, ripe sansuyu, seed, leaf, stem, and dried sansuyu). One active component, morroniside, was high in fruit (under-ripe and ripe sansuyu), while loganin was high in fruit (under-ripe sansuyu) and cornin was high in seeds. Total polyphenol contents were highest in fruit (ripe sansuyu) and flavonoids were highest in leaves. DPPH radical scavenging activity was highest in leaves, followed by seeds and then ripe sansuyu extract. The anti-inflammatory efficacy of leaf extracts of C. officinalis (LCO) was further investigated by measuring their effects on levels of nitric oxide (NO) and the pro-inflammatory cytokines interleukin (IL)-1β and IL-6 in RAW 264.7 macrophages. Non-cytotoxic concentrations of LCO effectively decreased the lipopolysaccharide (LPS)-induced expression of inducible NO synthase, resulting in decreased NO production. LCO also significantly suppressed LPS-induced production and expression of IL-1β and IL-6. Taken together, the present findings suggest that C. officinalis leaves have potential as natural materials for the development of antioxidant and anti-inflammatory agents.
Rutin, a group II phospholipase $A_2$ ($PLA_2$) inhibitor, was tested on interleukin-1 (IL-1) induced acute lung injury (ALI) in male Sprague-Dawley rats. Rutin did not alter the increased lung myeloperoxidase activity by IL-1. However, the number of neutrophils in bronchoalveolar lavage fluid (BALF) and IL-1 induced lung leak were decreased by rutin (p<0.001). Simultaneously, rutin decreased lung $PLA_2$ activity, which was increased by IL-1 (p<0.001). The reduction of neutrophilic respiratory burst by the inhibition of $PLA_2$ was confirmed by group II $PLA_2$ inhibitors such as rutin, manoalide and scalaradial. The increased level of cytokine-induced neutrophilic chemoattractant (CINC) in BALF by IL-1 was not affected by rutin. Ultrastructural changes of ALI and increased generation of free radicals in the lung by IL-1 were found, and rutin ameliorated these pathological findings. Taken together, rutin seems to be effective in decreasing IL-1 induced ALI through inhibition of group II $PLA_2$.
Objectives : The purpose of this study is to examine the effects of external application of HC001 on atopic dermatitis. HC001, newly composed herbal medicine combinations contains 9 medicinal herbs which are known to have anti-inflammatory and anti-allergic effects. We investigated the anti-inflammatory effects of HC001 on atopic dermatitis-like skin lesions in mice. Methods : Seven-week-old BALB/c mice were sensitized with DNCB to develop atopic dermatitis. Animals were divide into three group: Normal, DNCB (Negative control group), HC001 (Experimental group, treated with DNCB and HC001). Skin sections were stained with H&E to measure the thicknesses of the epidermis and dermis, respectively. The expression of NF-${\kappa}B$ protein was measured by western blotting analysis in skin lesion. Results : Topical HC001 treatment significantly restored the skin thickening and hyperplasia of the epidermis and dermis compared with DNCB-sensitized group in histopathological analyse. In addition, HC001 inhibited the expression of NF-${\kappa}B$ protein increased in DNCB-induced atopic dermatitis-like skin lesions in mice. Conclusions : These results suggest that HC001 may be useful as an external application agent for atopic dermatitis based on reductions of various inflammatory responses.
Objectives: Sprague-Dawley rats were fed with high fat diet, and atherogenic changes were seen in the aorta. However, when Sprague-Dawley rats were fed with a high fat diet and administered Youngyopaedoc-san together, these atherogenic changes were rarely seen. This study was aimed to find the inflammatory marker level changes in Sprague-Dawley rats with Youngyopaedoc-san-related anti-atherogenic effect. Methods: The extract from Youngyopaedoc-san was made by the pharmacy department of Kyung-hee Oriental Medical Hospital. The animals were divided into five groups: normal diet, high fat diet, high fat diet with Youngyopaedoc-san, high fat diet with Vytorin, and high fat diet with Youngyopaedoc-san and Vytorin. A light microscopic image of a cross section taken from the aorta of the Sprague-Dawley rat was analyzed. We compared inflammatory marker levels among the five groups. Results: The complex of Youngyopaedoc-san and Vytorin has more anti-atherogenic effects in the aorta of Sprague-Dawley rats fed with high fat diet than Vytorin alone. Youngyopaedoc-san has inhibitory effect on the increase of IFN-${\gamma}$ and IL-2 levels. The difference on eosinophil levels of each group was statistically significant, but the eosinophil level of each group was within normal limits, so the difference on eosinophil levels was not clinically significant. Conclusions: Youngyopaedoc-san-related anti-atherogenic effect could be a result of inhibitory mechanism on IFN-${\gamma}$ and IL-2.
This study was conducted to assess the effect of highly concentrated onion intake on rodents. The experimental animals were divided two groups as follows; water administered group (CON) and Allium cepa administered group (ACE). The ACE group showed a slightly increases in the number of erythrocytes (RBC), hemoglobin (HGB), hematocrit (Hct) levels compared to the control group (p<0.05). Hemoglobin, monocyte, lymphocyte and neutrophil had no significant change (p>0.05) in ACE group and control group. The analysis of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) levels showed a significant decrease in ACE group compared to the control group (p<0.05). The blood glucose, total protein, HDL-cholesterol were slightly high in ACE group, while triglyceride, total cholesterol levels were lower in ACE group compared to the control group (p<0.05). The levels of cytokines (interluekin-1α (IL-1α), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), interferon-γ (INF-γ), interleukin-18 (IL-18), interleukin-2 (IL-2), granulocyte-macrophage colony-stimulating factor (GM-CSF)) involved in immunity and inflammation in liver tissue and blood have all been confirmed to be within normal range. These findings could be used as basic data to show that highly concentrated dietary onion extract is not toxic to hematological indicators and immune functions.
