OBJECTIVE: This study has been conducted to determine the protein efficiency ratio (PER) of selected indigenous legumes, namely pigeon pea (Cajanus cajan) and lima bean (Phaseolus lunatus), as alternative protein sources.

METHODS: Experimental diets (pigeon pea-based and lima bean-based) and control diet (casein-based) were formulated and standardized using proximate analysis to have 10% protein basal diet based on the Association of Official Analytical Chemists (AOAC) guidelines. Diets were given to corresponding groups (2 experimental, 1 control) using 30 albino Sprague-Dawley weanling rats aged 21 days old, over a 28-day growth assay.

RESULTS: Results showed that the mean final weight and weight gain were significantly higher in rats fed with casein-based diet (p0.05). The PER of the casein (3.37 ± 2.71) is higher than that of the pigeon pea (1.87) and lima bean (1.32). These results can be attributed to the presence of anti-nutritional factors (ANFs) in the seeds of pigeon pea and lima bean. Reduced protein intake (due to bitter taste), toxicity, and interference with protein digestibility (through interaction with digestive enzymes) imparted by these ANFs can explain the weight loss among the experimental groups and consequently the low PER. Heat treatment done in the study were not adequate to remove the ANFs.

CONCLUSION: The study shows that pigeon pea and lima bean as protein sources alone are not as adequate and efficient in providing necessary protein requirements for weanling rats. Proper processing and treatment should be done to remove inhibitors of protein digestibility and quality.

OBJECTIVE: To determine the effectivity of Chitosan in the reconstruction of conjunctival defect created during surgical removal MATERIALS AND METHODS: Preparation of Chitosan biofilm. Chitin was isolated and purified from giant tiger prawn (Penaeous monodon) exoskeleton waste and converted to a 97 percent deacetylated form by reaction with 40 percent NaOH then dissolved in 0.1M acetic acid forming a chitosan-acetate solution. The solution was poured into a petri dish and dried forming a film. Animal Study. Conjunctival defects were induced by excising the conjunctiva (6 x 6 mm) of 32 rabbit eyes. Sixteen experimental eyes received the chitosan biofilm sutured in continuous fashion using 8-0 conjunctiva, where the previous incision was made, were harvested and sent for histopathology to look for re-epithelialization and fibroblast formation. Wilcoxon Matched-Pairs Signed-Ranks Text was utilized in data analysis RESULTS: Epithelial growth was significantly higher in the Chitosan treated group as compared to the control (p0.05). Fibroblast formation was likewise significantly higher in the Chitosan treated group than in the control CONCLUSION: Chitosan is effective in promoting re-epithelialization and fibroblast formation and can thus be used as a possible alternative in ocular surface reconstruction.

PURPOSE: The purpose of this study was to determine current trends and the mode of future development in the field of medical radiology and to promote research among the nation's radiologists by analyzing the contents of the Korean Radiologic Society(JKRS) and Radiology. MATERIALS AND METHODS: The number of articles published in JKRS each year between 1990 and 1994 was counted. The research articles in JKRS(n=740) and in Radiology(n=1748) between 1992 and 1994 were categorized according to the objective, type, topic, materials, and radiologic techniques of their contents on the basis of predetermined criteria. Domestic Masters theses(n=126) and doctoral dissertations(n=75) accepted between 1990 and 1994, and domestic materials published in international journals(n=416) between 1986 and 1994 were also categorized using the same criteria. RESULTS: The greatest increase in the number of articles published in JKRS was seen during 1994. The majority of these aimed to retrospectively analyse the findings of diseases while the majority of articles published in Radiology dealt prospectively with the development and/or evaluation of diagnostic methods. More variety of topics and issues was seen in Radiology than in JKRS. The number of articles of domestic materials published in international journals increased from1986 to 1994, while the number of articles of foreign materials published in korea was relatively stationary. A significant number of theses and dissertations dealt, mostly prospectively, with studies of pathophysiologic and/or pharmacologic mechanisms using animal models. CONCLUSION: In order to understand both current trends and the direction and mode of future developments in the field of radiology, and to be able to actively deal with challenges at the forefront of radiologic development, it is essential to review research articles published in radiology-related journals.

Introduction on the factors influence dosage that is equivalent in effectiveness between animals. They comprised drug metabolism, minimum concentration have with effect in serum, the effective time, cellular respiration, organic weight rate comparison with body weight, heat production, cytochrom C, volume of kidney and body surface.

A study on the roborant effect of drug by swimming test in the experimental rat or mice was carried out. The swimming time calculated from standing swimming until rat was exhausted that can not swim. There were 2 method of calculation, including average swimming time and second swimming time comparing with the first swimming time.

The study was carried out on 100 healthy rats, weight of 12020g which were divided into 10 groups. Raw materials: BB103 pure powder and mefloquine. Results: In rats received BB103 with doses of 50 mg/kg and mefloquine 50 mg/kg in 5 days, there were no significant changes on process of conditioned reflex, speed of reflex establishment was stable, response time and extinguishing time of reflex were similar to those of the control group (p>0.05). In rats received BB103 with doses of 100 mg/kg and mefloquine 100 mg/kg in 5 days, there were significant changes on speed of reflex establishment and response time (p<0.01-0.05). There were differences on speed of reflex establishment, speed of stable reflex in rats received BB103 and mefloquine (p<0.01-0.05)

Antioxydant effect of radix notogingseng fluid extract 1:2 was studied in mice. Experiment mice were divided randomly into 3 groups x 10 animals. Control group (group 1) was given orally with NaCl 0,9% + oliver oil infiction, group 2 was given orally with NaCl 0,9% + CCl4 infection, group 3 with notogingseng extract 5g/kg of mice. Results showed the antioxydant effect of notogingseng at moderate level. It increased the liver GSH content in comparing with intocicated group.
