  • The purpose of this study was to know the effect of aquatic-exercise on muscle atrophy which induced by steroid injection. The forty-eight Sparague-Dawley adult male rats were assigned to the 4 groups; GroupI(distilled water injection), GroupII(steroid injection), GroupIII(distilled water injection and aquatic exercise), GroupIV(steroid injection and aquatic exercise). We observed their body weight, histological change by PAS stein. The results of this study were as follows; 1. After 2 weeks, the change of weights appeared that non-steroid injection groups increase weight and steroid injection groups decreased weight hasty. after 4 weeks, weights recovered from weight before test. It was possible to explain the change of weight by type II muscle fiber increase. 2. In histological change of muscle fibers, atrophy didn't observed in test group I, because type II muscle fibers were developed well. we observed not only injury of muscle fiber and muscle atrophy but specifically grouping type I muscle fiber in test group II. normal arrangement of muscle fibers were visible in test group and type II muscle fibers increased. we could observe muscle recovery because of type II muscle fibers increase in test group IV. therefore, it was seem that type II cell was recovering through aquatic exercise.

  • Follicle stimulating hormone (FSH) stimulates follicle growth, and inhibits the follicle atresia in the immature rodent ovaries. The present study was carried out to know the histological changes of ovarian follicles after FSH treatment in the prepubertal mice. Ten i.u. of recombinant FSH was i.p. injected on 3 weeks old mice. After the treatment, at 1, 2 and 3 days, left ovaries were collected for the histological study. The atretic ratio of preantral follicles increased with time after FSH treatment. However, in the case of antral follicles, there was no significant change in the ratio. The degenerating follicles contained apoptotic granulosa cells, macrophage, and polymorphonuclear leukocytes in the follicular cavity. The present results suggest that follicular degeneration caused by FSH hyperstimulation could be mediated by apoptosis as well as the acute inflammation.

  • This study was carried out to test the recuperative effect of 2 types of sample drugs for 3 degree burn. The burn injury was made by iron plate heated in the boiling water. The Sprague Dawley rats were shaven with a razor preliminarily and burned by direct contact method for 10 seconds. The experimental groups were classified with 5 each-normal, control, MEBO ointment, sample A, sample B. The effect of the sample drugs were decided by histological results after 3 week application. The results were as following. The 3 treatment groups recovered the burn injury faster than control group. The recuperative effect precedes about 4-5 days at the time of 15th day and 1 week at the time of 3rd week. The therapeutical procedure of 3 treatment groups was similar with naked eye and with microscopic histology in the 1 st, 2nd and 3rd specimens. So there weren't significant differences in curative effect in 3 treatment groups of this experiment. But a regeneration of hair follicle was noted in Sample B uniquely. These results suggested that 3 burn remedies have similar effect of therpy, but sample B containing yolk sac oil has slightly better effect in part of hair regeneration.

  • Objectives : This study aimed to elucidate the effects of TBE on hyperlipidemia. Methods : We studied the effects of TBE on hyperlipidemia through gene expressions related with lipid metabolism and serum triglyceride as well as total and HDL-cholesterol levels, and perceived histological changes. Results : The present studies demonstrate that TBE can reduce the rise in plasma cholesterol and TG levels induced by a high-cholesterol diet and also reverse pre-established hypercholesterolemia and hypertriglycemia. In the TBE group total cholesterol levels decreased, TG levels decreased, but HDL-cholesterol levels also decreased. In the analysis of absolute and relative liver weight, TBE inhibited the weight gain induced by a high-cholesterol diet. In the histological observations, lipid droplet and apoptotic change in the TBE treated group were less compared with the control group. In the serum biochemical analysis, a difference of serum AST and ALT changes among groups was not shown, but TG and total cholesterol levels were less and HDL level decreased compared with the control group. In the gene expression related with TG and cholesterol metabolism, DGAT decreased slightly but ACAT decreased more as compared with control and Lipidil groups. Conclusion : From this study, we can infer that TBE possesses a hypolipidemic effect by inhibiting the intestinal absorption and storage of exogenous and endogenous cholesterol.

  • Aim: To evaluate the predominant colorectal polyps in the Almadinah region of Saudi Arabia. Materials and Methods: In this iretrospective study, we analyzed pathology reports of colonoscopies performed in King Fahad Hospital, Madinah, Saudi Arabia during the period 2006 to 2013. Data based on patient age, gender, size, site and type of polyps and the degree of dysplasia were analyzed by software SPSS 17 and compared with other published studies from different geographic regions of the world. Results: During these years, 224 patients had colonic polyps, of whom 149 (66.5%) were men and 75 (33.5%) were women. The most common types of polyps were adenomatous (166), followed by hyperplastic polyps (24), juvenile (18), inflammatory (13), lipomatous (2) and one patient with Peutz-Jegher polyps. Tubulovillous adenoma was the commonest adenomatous polyp (102), followed by tubular (41) and villous (23) types. The sigmoid colon was the most commonly involved region (36.6%). Dysplasia was significantly associated with female patients who had large size tubulovillous polyps located in the left colon. Conclusions: The type and distribution of colorectal polyps in Saudi Arabia is very similar to Western countries. Patient gender, and size, histological type and location of polyps are closely related to dysplastic change in colonic polyps.

  • Background: Endometrial cancer is the fourth most common cancer among women in developed countries. Patients with endometrial cancer may benefit from systemic chemotherapy alone or in combination with targeted therapies if the disease is clinically diagnosed prior to spread and metastasis to other organs. The aim of this study was to evaluate the prognostic role of p53 polymorphism and its correlation with tumor grade in human uterine endometrial carcinomas. Materials and Methods: A total of 75 patients with endometrial carcinomas were studied for possible mutations in exon 4 of the p53 gene using polymerase chain reaction and restricting fragment length polymorphism techniques and sequencing. Results: In recent study, The rate of homozygote genotype of pro/pro or Arg/Arg in high grade group was higher than in comparison with low grade one. In addition samples that were undigested in RFLP, showed mutation in exone 4. Conclusions: Our findings showed that high grade endometrial carcinomas are highly associated with TP53 polymorphisms in comparison with low grades.

  • The decrease of masticatory function caused by tooth loss leads to a decrease of cerebral blood flow volume resulting in impairment of cognitive function and learning memory disorder. However, the reduced mastication-mediated morphological alteration in the central nervous system (CNS) responsible for senile deficit of cognition, learning and memory has not been well documented. In this study, the effect of the loss of the molar teeth (molarless condition) on the hippocampal expression of glial fibrillary acidic protein (GFAP) protein was studied by immunohistochemical techniques. The results were as follows : 1. The molarless mice showed a lower density of pyramidal cells in the cornu ammonis 1 (CA1) and dentate gyrus (DG) region of the hippocampus than control mice. 2. Immunohistochemical analysis showed that the molarless condition enhanced the time-dependent increase in the cell density and hypertrophy of GFAP immunoreactivity in the CA1 region of the hippocampus. The molarless condition enhanced an time-dependent decrease in the number of neurons in the hippocampal formation and the time-dependent increase in the number and hypertrophy of GFAP-labeled cells in the same region. The data suggest a possible link between reduced mastication and histological changes in hippocampal formation that may be one risk factor for senile impairment of cognitive function and spatial learning memory.

  • Objectives In the theory of Korean Medicine, Cicadae Periostracum (CP) has been used to treat skin diseases such as inflammatory dermatitis, tetanus and pruritus. CP can reduce heat and disperse wind. In prior studies, anti-allergic effect and anti-inflammatory effect of CP were reported. However, there has been no report regarding the correlation of CP and allergic contact dermatitis (ACD). This study was performed to show the effects of CP in ACD induced by 2,4-dinitrochlorobenzene (DNCB) in mice. Methods In this experiment, the effects of CP on biological changes were measured, such as changes in ear and spleen weight, ear and dorsum skin thickness, clinical aspect on the dorsum skin and histological changes. The effect of proliferation rate of splenocytes was also investigated in vitro and vivo study. Results In results, CP application (CPA) group and CP application and administration (CPAA) group were significantly restrained in ear weight gain and increase in ear and dorsum skin thickness compared to the control group. In addition, CPA and CPAA group showed diminished erythema, desquamation, bloodstain, and marks. Also, the histological assessment showed that CP treatement diminished thickness of epidermis, hyperkeratosis, pigmentation and parakeratosis. Conclusions In conclusion, these data suggest that CP can decrease symptoms of ACD.
