  • In the rats administered mercuric chloride (1mg/kg/48 hrs i.p.), it was found that LDH$_{1}$ and LDH$_{2}$ were increased in heart, brain and kidney as well as LDH$_{5}$ increased in liver and muscle in the duration of sixteen days. After the sixteen days of administration, the LDH isozyme patterns in the above mentioned organs were found to be irregularly changed. Considerable amount of mercury accumulation in liver and kidney were found, and especially the mercury accumulation in kidney was notable.

  • This study was undertaken to investigate the effect of indomethacin on the distribution of Langerhans cells and T-lymphocytes related with immune response of 4-Nitroquinoline-1-oxide induced carcinogenesis at the palate and tongue of albino rat. 54 Sprague-Dawley strain 10 weeks old albino rats, about 150gm weighted, divided into a normal group of 6 rats without treatment, a control group of 12 rats given indomethacin, a carcinogenesis group of 18 whose palatal mucosa were appiled with 4-Nitroquinoline-1-oxide three times a week, and experimental group of 18 rats were treated with indomethacin and whose palatal mucosa were applied 4-Nitroquinoline-1-oxide. All these 54 rats were subjected to be observed as being ATPase stained specimens, specimens for the observation of light and electron microscope, and T-lymphocyte stained specimens. The obtained results were summarized as follows; 1. In carcinogenesis group, proliferation of epithelial layer and rete peg were observed early period of the experiment and showed parakeratosis, individual cell keratinization, acanthosis, and lymphocyte infiltration from 13th week of the experiment on lightmicroscopically, while experimental group showed less reaction than that of carcinagenesis group. 2. The number of Langerhans cells in normal group rarely changed until 21st week of the experiment, while the Langerhans cells increased markedly from 3rd week of the experiment in control group. 3. The number of Langerhans cells were decreased markedly and persistantly until 21st week of the experiment both in carcinogenesis and experimental groups. 4. Appearance of the T-helper cells and T-suppressor cells were minimal and irregullar in number both in normal and control groups. Thus it is assumed that administration of indomethacin and distribution of Langerhans cells showed close relation. 5. In carcinogenesis and experimental groups, the number of the T-helper cells was apparently inereased than that of the T-suppressor cells, but increasing pattern in experimental group was less than in carcinogenesis group. These cells increased most in the 21st week, decreased from the 23rd week and the appearance of these cells were irregular in general throughout the experiment.

  • The therapeutic effects of praziquantel on Fibricola seoulensis infection were studied by experimental infection of albino rats with the metacercariae obtained from the snakes. Total 51 albino rats were infected each with 500 or 1, 000 meta cercariae in number through intragastric tubes. One or four weeks la er the rats were treated with 1, 5, 10 or 20 mg/kg single dose of prazipuantel and sacrificed after 3 days or 10-120 minutes to search for the worms in their small intestine. The worm recovery rate at 3 days after the treatment was 10.7 % in 1 mg/kg dose group and o. 03~0.2% in 5, 10 and 20 mg/kg groups, while that of untreated control was 51. 3%. The minimum effective dose to treat F. seoulensis infection in the rats is considered to be 5 mg/kg in single dose. By observing the distribution pattern of worms in the small intestine after the treatment, dislodgement of the worms from the duodenum, their normal habitat, to the lower portions was recognizable within as early as 10 minutes. The majority of worms was found to have descended to the ileo-caecal portion after 60-120 minutes.

  • Neodiplostomum seoulensis, one of the human intestinal trematodes , was reinfected to albino rats, and worm recovery rates, histopathology and activity changes of the intestinal brush border membrane bound enzymes were observed. The experimental groups were three: uninfected, primary infection and reinfection. The worm recovery rate in the reinfection group was much lower than in the primary infection group 14 days after infection. The duodenal histopathology showed villous atrophy during the first and second week in the primary infection group. In the reinfection group, however. villous changes occurred as early as 3 days after the infection, and the lesion was found healed 7 days after infection. The activities of alkaline phosphatase and sucrase in the duodenum of primary infection rats decreased nearly half of the controls 2 weeks after infection, whereas the activities were unchanged in the reinfection group. However, no changes in the activities were observed in the proximal jejunum between the experimental groups. These findings suggested that a secondary infection of N. seouLensis in rats should make less damage on the intestinal mucosa than a primary infection. Key words: Neoniplostomum seoulensis, albino rats, reinfection, worm recovery, histopathology, brush border membrane bound enxyines.

  • In a project to study the hepatroprotective effect of some plant extracts four plants Ephedra foliate Boiss, Alhagi maurorum Medikus, Capsella bursa-pastoris (L.) Medik. and Hibiscus sabdariffa L. were studied. The ethanol extract of the aerial part of the first three plants and the flowers of H. sabdariffa were subjected to hepatoprotective assays using Wistar albino rats. Liver injury induced in rats using carbon tetrachloride. The biochemical parameters; serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP) and total bilirubin were estimated as reflection of the liver condition. Based on the good results of the biochemical parameters measurements, histopathological study was performed on the liver of rats treated with E. foliate. The normal appearance of hepatocytes indicated a good protection of the extract from carbon tetrachloride hepatotoxicity. All the results were compared with silymarin, the reference hepatoprotective drug.

  • BACKGROUND: The purpose of this study was that serum metabolic and hematological variables were measured to investigate the detoxication effect of Taraxacum mongolicum extract on male albino rat exposed with lead and mercury. METHODS AND RESULTS: For this study, Pb and Hg-exposed( 50 ppm) albino rats was used, and the treatments were carried out in three doses of 100 mg/kg, 200 mg/kg and 500 mg/kg as dry weight of T. mongolicum extract. T. mongolicum extract could improved the body weight gain and feed efficiency ratio, except to food intake. The levels of biochemical factors elevated by Pb-Hg mix exposure, which are Bilirubin, Alkaline phosphatase(ALP), glutamic oxaloacetate transaminase(GOT), glutamic pyruvate transaminase (GPT), lactate dehydrogenase(LDH), ceatinine and blood urea nitrogen(BUN), were significantly reduced in all treated groups as compared to Pb-Hg mix exposure alone. T. mongolicum extract was shown to suppress the accumulation of Hg and Pb in serum by dose dependent manner. CONCLUSION: Therefore, this study suggest that T. mongolicum extract might have the potential effect to minimize the toxic effects of Pb and Hg.

  • cis-Dichlorodiammineplatinum (II) (cis-Platin) inhibits the proliferation and growth of the tumor cells by way of inhibiting DNA and protein synthesis of the cancer cells. Although cis-Platin is very effective antitumor drug, it also produces many other side effects. Thus the author has studied the effects of cis-Platin on the proximal epiphyseal plate in the tibia of the rat. The results were as follows: In the chondrocyte of the proliferative zone, sacculated, and fragmented cisternae of rough endoplasmic reticulum, some mitochondria with disorganized mitochondrial cristae and distorted procollagens were observed, and in the matrix some large matrix granules and dispersed collagen fibrils were revealed on the 1st, 3rd day and 1st week group of cis-Platin treated rats. In the chondrocyte of the proliferative zone of cis-Platin treated rats on the 2nd and 3rd week group, parallely arranged rough endoplasmic reticulum and many procollagens were shown, and in the matrix a number of large matrix granules and many small matrical granules as well as collagen fibrils were revealed. Consequently it is suggested that though cis-Platin induces the degenerative changes of the chondrocyte resulting in components of the cartilagenous matrix, these toxic effects are regressed with time.

  • Madhuca indica has been used ethnomedically in Indian folks. In the present study we have investigated anti-inflammatory, anti-ulcer and hypoglycaemic effect of ethanolic extract (EE) and crude alkaloid extract of Madhuca indica seed cake on albino rats. The study showed that the EE had a significant, dose dependent anti-edematogenic, anti-ulcerogenic and hypoglycaemic activity, whereas the crude alkaloid extract exhibited a significant only. Both the extracts possess dose dependent inhibitory activity on carrageenan-induced edema, inhibiting prostaglandins or mediators involved in prostaglandin synthesis, the second phase of inflammation. The EE was significantly effective in protecting pylorus-ligation-induced gastric ulcers at a higher dose level. The active principle of EE seems to be a selective inhibitor of the COX II (prostaglandin synthesis) without important effect on COX I since, EE exhibited both anti-edematogenic and anti-ulcerogenic effect. The EE was effective in reducing the plasma glucose level in normal albino rats in a dose dependent manner, producing hypoglycaemic effect by stimulating the release of insulin from the ${\beta}-cells$ and/or increasing the uptake of glucose from the plasma.

  • Ayurveda, an ancient System of Indian Medicine, has recommended a number of drugs from indigenous plant sources for the treatment of inflammation. To evaluate the anti-inflammatory and analgesic activities of methanol extract of Triphala were investigated in Wister albino rats and mice. The methanol extract of Triphala were found to encompass substantial anti-inflammatory effect in acute and sub-acute models and analgesic effect. Animal models of carrageenan induced edema and cotton pellet induced granuloma in albino rats were used. Extract of 200 mg/kg shows significantly reduced paw edema. Analgesics activity of Triphala with 200 mg/kg shown by significant reduction of writhing. These report shows to support the use methanol extract of Triphala in relieving inflammation and pain.
