  • Alcohol is a major risk factor for several diseases and excessive, long-term alcohol consumption are caues physical alteration-fatty liver, hepatitis, cirrhosis, breaking down, Wernicke-karsakoff's syndrome, weight loss, and poor immunity-in virtually all organ and tissue. This study was observed that liver, kidney, and stomach were altered in mouse by the effect of chronic alcohol administration. The mouse were sacrificed to obtain the tissue after mouse were orally injected with 25 % ethanol $18m{\ell}/kg/day$ for 120days. The tissue were stained by hematoxylin and eosin and then observed by light microscope. The results of this study were as follows : 1. The congestion was appeared in liver after 120days alcohol admistration. 2. The destruction of glomerulus were increased and the parietal cell of Bowman's capsule were swelled such as cuboidal cell after 120days alcohol administration. The congestion was appeared in alcohol administrated group. 3. The mucosa and gastric pit were destructed and the ulceration was appeared in stomach after 120days administration. The parietal cells and chief cells were damaged. Above results were shown that the tissue were damaged by chronic alcohol administration.

  • The purpose of this study is to analyze that ICT-based primary health care affects clinical changes of participants in the primary care chronic disease management pilot project using ICT medical care. Customized health information data, provided by National Health Insurance Service, was used for the analysis. The study targeted a total of 676 people that participated in primary care chronic disease management pilot project using ICT medical care from 2017 to 2018. Hierarchical regression was used to test three model. First, there were many subjects who used face-to-face consultation and non-face-to-face consultation(messaging), but less than half of patients using non-face-to-face consultation(telephone). Second, after participating in the pilot project, the fasting blood sugar level decreased. Third, the clinical condition of the subjects appeared to be an important factor in controlling blood sugar levels. Finally, patients using the non-face-to-face consultation(messaging) had reduced blood sugar levels after participating in the project. This results imply that non-face-to-face consultation is effective in reducing fasting blood sugar level with hospital intervention, and there are effects of the primary care chronic disease management project using ICT.

  • Many diabetic patients develop serious complications during the course of the disease, including cardiovascalar disorders, nepropathy, neuropathy and retinopathy. Because some physiological changes occurring in diabetes mellitus patients could alter the pharmacokinetics of drugs used to treat the disease, the pharmacokinetics of gentamycin was investigated after intravenous administration (2 mg/kg) to control rabbits and acute or chronic alloxan-induced diabetes mellitus rabbits (AIDRs). After intravenous administration, the serum concentrations of gentamycin were significantly higher between 6 and 12 hr in chronic AIDRs compared with those in control rabbits. The AUC was significant greater in chronic ($31.91\;{\pm}\;3.76\;{\mu}g/ml{\cdot}hr$) AIDRs than that in control ($21.60\;{\pm}\;2.45\;{\mu}g/ml{\cdot}hr$) rabbits. Total body clearance (CLt) in AIDRs were significantly decreased compared with that in control rabbits. Cumulative urinary excretion of gentamycin was decreased, although not significantly, in AIDRs compared with that in control rabbits.

  • Purpose: Chronic nicotine administration induce various effects in whole organs of the body; however, little is known about salivary gland. In the present study, we pursued the links between systemic nicotine and the histomorphological changes of the salivary gland in mice. Methods: Twenty-five C57BL6 mice were allocated into two groups. The control group (n=9) received distilled water only for 8 weeks by gavage. The experimental nicotine group (n=16) was administered nicotine $5{\mu}g/g$ with distilled water. Animals were sacrificed at 8 weeks; then, submandibular glands were excised and processed for histologic evaluation. Volumetric changes in acinar cells were evaluated by H&E staining. The expression of calponin-positive myoepithelial cells and Ki-67-positive proliferating acinar cells were evaluated by immunohistochemistry. Results: The nicotine group showed significantly decreased number of calponin-positive myoepithelial cell process compared with the control group. There were no significant differences in average volume of acinar cell and the number of Ki-67-positive acinar cells between both groups. Conclusions: These findings suggested that chronic nicotine administration may cause decreased function of myoepithelial cells in submandibular glands of mice, and these can partly explain xerostomic conditions in chronic smokers.

  • This study was conducted to investigate the antitoxic effects of Radix Menispermi extracts against cadmium toxicity. The experimental rats were divided into 5 groups such as control group, cadmium alone treatment group and simultaneous treatment groups of cadmium and three doses of Radix Menispermi extracts. Each group was administered with different dose of Radix Menispermi extracts such as 0.55 mg, 1.10 mg, 1.65 mg/kg wet weight in pallets for 12 weeks. Cadmium Chloride $(CdCl_2)$ was administered by 4 mg/kg body weight. The results were summarized as follows: 1. The simultaneous administration of cadmium and Radix Menispermi significantly more decreased cadmium concentration in liver tissues compared to the administration of cadmium only (P < 0.05). 2. When blood were measured, no significantly difference in haemoglobin, haematocrit, erythrocyte values compared to the administration of cadmium only. 3. The simultaneous administration of cadmium and Radix Menispermi more increased metallothionein concentration in liver than the administration of cadmium only (P < 0.05). 4. There were the histopathological slight changes in the liver and kidney tissues of rats.

  • Morphine has been used widely on the treatment of many types of chronic pain. However the development of tolerance to morphine by repeat application is a major problem in pain therapy. The purpose of the present study was to investigate whether combined administration of nalbuphine with morphine affects the development of tolerance to and dependence on morphine. We hypothesize that the use of nalbuphine, k-agonist may prove to be useful adjunct therapy to prevent morphine-induced undesirable effects in the management of some forms of chronic pain. Morphine (10 mg/kg) was injected to rats intraperitoneally for 5 days. The variable dose of nalbuphine (0.1, 1.0 and 5.0 mg/kg) was administered (i.p.) in combination with morphine injection. The development of tolerance to morphine was assessed by measuring the antinociceptive effect with the Randall-Selitto apparatus. The development of dependence on morphine was determined by the scoring the precipitated withdrawal signs for 20 min after injection of naloxone (10 mg/kg, i.p.). Nalbuphine did not attenuate antinociceptive effect of morphine in rats. Interestingly, combined administration of morphine with nalbuphine (100:1) significantly attenuated the development of morphine tolerance and dependence. These results suggest that the co-administration of nalbuphine with morphine in chronic morphine treatment can be one of therapies to reduce the development of dependence on morphine.

  • Acute and chronic effects of ethanol (EOH) administration on the cardiovascular and hormonal responses to repeated hemorrhage were investigated in conscious normotensive Wistar rats and spontaneously hypertensive rats (SHR). The chronic EOH treated group received 5% EOH (vol/vol) ad libitum in the drinking water far the first week,10% for the last 2 weeks, and 20% for the last 5 weeks from the age of 6 weeks. The EOH free group received tap water. Chronic EOH and EOH free groups were randomly subdivided into acute EOH infusion and control groups. Under ether anesthesia, catheters were inserted into the femoral vein and both femoral arteries. After rats regained consciousness and their blood pressure was stabilized, responses to quick hemorrhage (5 ml/kg BW) were tested. In the acute EOH infusion group, hemorrhage was induced 20 min after EOH infusion (1.0 g/kg BW), Baroreceptor reflex sensitivity was assessed by the ratio of changes in hen.1 rate and mean arterial pressure (${\Delta}HR/{\Delta}MAP$) immediately after the hemorrhage. Chronic EOH administration elevated MAP in Wistar rats. During acute EOH infusion, MAP do- creased and HR increased in all groups. In comparison to EOH free control rats, acute or chronic EOH treated rats showed a greater reduction in MAP and a smaller elevation in heart rate in response to a hemorrhage. The degree of MAP reduction was significantly greater in SHR than in Wistar rats. Both the acute and chronic EOH administration attenuated the baroreceptor reflex and retarded MAP recovery, again the trend being much more prominent in SHR. The increase in plasma vasopressin and lenin concentrations after hemorrhage were intensified by the chronic EOH administration. SHR showed a greater vasopressin response but a smaller lenin response than Wistar rats. These results indicate that the EOH treated rats, particularly SHB, are prone to shock by a hemorrhage, which may be partly attributed to an impaired baroreceptor reflex function.

  • This study was to investigate the hepatoprotective and anticirrhotic effects of Ganyeumilhobang(GIE) on the acute and chronic liver injury induced by various agents. Chronic liver injury induced by dimethylnitrosamine(DMN) ; a new experimental model for cirrhosis and the intraperitoneal injection of dimethylnitrosamine in the rat. Acute liver njury induced by carbon tetrachloride$(CCl_4)$ and D-galactosamine ; a experimental model for acute liver injury, the administration of $CCl_4$ and the intraperitoneal injection of D-galactosamine in the rat. The development of fibrosis and acute liver injury by the three prescriptions were examined by the chemical analysis of AST, ALT, prothrombin time and hydroxyproline. The results obtained were as follows. 1. The increasing level of hydroxyproline volume induced by DMN in mice was decreased by the oral administration of GIB. 2. The degree of histological fibrosis and hepatic inflammatory cell infiltration induced by $CCl_4$ decreased by the oral administration of GIB. 3. The increase of senun AST and ALT of mice with acute liver damage induced by $CCl_4$ and D-galactosamine was inhibited by the administration of GIB. 4. The prolongation of prothrombin time(seconds) of mice acute liver damage induced by $CCl_4$ was shortened by the oral administration of GIB. 5. The liver of mice was hepatectomized partial1y after the oral administration of GIB. The mitotic index(% of nuclei), weight of liver, contents of protein, RNA and DNA synthesis of the liver tissue were increased by the oral administration of GIB.

  • Angiotensin receptor blockers, such as telmisartan, are considered effective in the treatment of hypertension and proteinuria due to chronic kidney disease (CKD) in cats. It selectively blocks the $AT_1$ receptor and does not affect the $AT_2$ receptor, thus effectively blocking the activity of the renin angiotensin aldosterone system. This study aims to compare over time the changes in various indicators, including systemic hypertension and proteinuria, before and after the administration of telmisartan in cats with CKD. Decrease in blood pressure (BP) (p<0.001) and urine protein to creatinine (UP/C) ratio (p<0.001) were found to be statistically significant over time after the administration of telmisartan. BP and the UP/C ratio were $160{\pm} 22.2$ and $0.50{\pm}0.647$ before telmisartan administration (Day 0), $150{\pm}21.0$ and $0.27{\pm}0.487$ on the 30th day (Day 30), $150{\pm}17.0$ and $0.25{\pm}0.376$ on the 60th day (Day 60), and $140{\pm}17.8$ and $0.15{\pm}0.233$ on the 90th day (Day 90) after administration, respectively. BP and UP/C were statistically significantly lower in cats with CKD over time at each time point from Day 0 to Day 90 at 30 day intervals. Especially after 90 days of telmisartan administration, the improvement of BP and UP/C were estimated to be about 20 mmHg and 0.35, respectively. In conclusion, the oral administration of telmisartan to cats with CKD is effective in improving BP and proteinuria, which has a positive effect on long-term survival in cats with CKD.

  • This study aimed to investigate the relationship between the health behavior and prevalence of chronic disease in 5,638 city workers. Data were analyzed with frequency, percentage, chi-square test, logistic regression analysis. The results showed that the health behaviors of the subjects were high smoking and drinking, low exercise, and the prevalence of chronic diseases was high in obesity and hyperlipemia. The major influencing factors of chronic diseases were age, exercise and drinking. This study suggests that it is necessary to operate a systematic health management program for the desirable health behaviors in the national, local, and industrial fields.
