Plasma levels of growth hormone(GH), luteinizing hormone(LH) and cortisol were determined by radioimmunoassay following radiofrequency(RF) stimulation or coagulation of various nuclei in thalamus and hypothalamus. RF stimulation or coagulation of many nuclei in thalamus and hypothalamus consisted of pulvinar and dorsomedial nucleus in thalamus and anterior and posterior hypothalamic nuclei in hypothalamus. Anterior thalamic stimulation resulted in highly significant increase of plasma LH, GH, cortisol and TH levels. However thalamic stimulation resulted no change in the level of various plasma hormones. Hypothalamic lesion produced significantly decreased plasma LH, GH and cortisol levels. Plasma cortisol and LH levels were highest 2 hours after stimulation while GH levels did not increased until 6 hours and TH until 72 hours respectively after stimulation. The significant difference in latency for beginning of hormone secretion suggests that GH, cortisol and LH may be controlled by several separate neuronal networks. Plasma GH and cortisol levels were lowest 72 hrs after coagulation of the anterior hypothalamic area, while GH, cortisol and LH levels did not change following stimulation or coagulation of posterior hypothalamic nucleus and thalamic nucldi. It was also noted that the anterior hypothalamic stimulation or coagulation caused increased or decreased in GH, cortisol, and LH than that observed from stimulation or coagulation of other hypothalamic and thalamic nuclei respectively.

Multifocal choroiditis and panuveitis(MCP) is a clinical syndrome characterized by vitritis, and punched-out fundus lesions mimicking presumed ocular histoplasmosis. We diagnosed MCP in a twenty-eight years old woman with the complaint of decreased vision and floater symptom. Retinochoroidal anastomosis via one of retinochoroidal scars was noted in this case. The patient was treated with oral and periocular steroid and ws observed for 11 months during which choroidal neovascularization and macular edema ws not developed. We present this case because, as far as our knowledge goes, There has been no reported case of MCP with retinochoroidal anastomosis.

There are several methods for diagnosis of leprosy, including AFB stain, the measurement of PGL-1 (phenolic glycolipid - 1) antigen titer, and DNA-PCR. In this study, we have used the DNA-PCR amplifying the RLEP repetitive sequence. Our result showed that the RLEP primer offered the more sensitive detection and identification of M. leprae DNA in clinical specimens, compared with the other primer, for example, 18-kDa antigen gene. To screen the resistant M. leprae strain of MDT (Multi-Drug Therapy), we have used the TD (Touch-Down) PCR. We arranged and amplified sequences of the genes, folP, rpoB, gyr, 23S rRNA, in M. leprae involved in MDT-resistance, and could obtain the PCR product each gene, simultaneously. This method, based on annealing temperature, was useful to the detection for diagnosis and the screen of MDT-resistant strain of M. leprae, rapidly. Thus, we suggest that the RLEP primer and TD-PCR method are effective in assessing the diagnosis of leprosy and the identification of drug-resistant M. leprae.

The short time antibacterial effect of tetracaine hydrochloride was studied. S. aureus, Coagulase Negative Staphylococcus and P. aeruginosa were each incubated with tetracaine hydrochloride(preservative free) for 18 hours or for 2 minutes and then diluted and cultured on nutrient agar plate. Colony counts were done after 18 hours. In cases of 18 hours incubation, there was no growth of microbials in 0.5%, 0.1% tetracaine hydrochloride, but there was no inhibitory effect of 0.02% of tetracaine hydrochloride on growth of microbials, irrespective of inoculum amount. In cases of 2 minutes incubation with 0.5% tetracaine hydrochloride, there was no difference between the amount of microbial inoculum and colony count. Above in vitro study indicates that tetracaine hydrochloride has no inhibitory effect on bacterial growth in short time exposure less than 2 minutes.

Depression is one of most frequent psychiatric disorders in the elderly. Major depression has higher prevalence in the elderly compared with younger subjects. Depression in the elderly is a major health concern that can be life threatening, if not recognized and not treated. An untreated depression may result in needless suffering, institutionalization, and suicide. Inadequated treatment may occur because the signs and symptoms of depression in the elderly are different from those in the young, and because the depressive symptoms may be viewed by the physician as a normal part of aging. The purpose of this study is to evaluate depressive factors in the Korean elderly. Four hundred and sixty eight Koreans were evaluated for depressive factors in 60 years old or more. The author performed a clinical evaluation guide, an intensive questionnaire, and Mini-Mental Status Examination-Korean version (MMSE-K). Stastically ANOVA, Scheffe, Duncan and Chi-square methods were used to find out depressive factors in the Korean elderly. Depression, dissatisfaction, suicidal idea and distress factors were evaluated in the Korean elderly depressed persons. Depressive factors were associated with physical health problems, family problems, psychiatric health problems, loneliness, economic problems, interpersonal conflicts, and occupational problems. Among these depressive factors, physical health problems were most frequently dominant in the elderly. Physical health problems are closely related to depression in the elderly. Depressive syndromes in the elderly are frequently combined with somatic complaints. And depression may be masked by multiple somatic complaints or by pain, for which no organic cause can be found. However, the etiology and mechanism of the association between physical illness and depression are unkown. Such factors as described above may be important in reducing the high prevalence of depression in elderly people.
