A study was made of the differences in clinical features and immunological aspects between herpes zoster patients with malignancies and those without malignant tumors. The results obtained from the retrospective review of medical records are as follows: Herpes zoster occurred more frequently in younger patients(less than twenty) with malignanciee as compared with the control group of the same ages,' Male was dominant among zoster patients with malignancies as is the contrary to contral group; Tihere were no marked differences in primarilly involved dermatomes between the two groups; Generalized varicelliform eruptiona were more common in zoster pa,tients with malignaneies than in control group, It seemed that zoster patients with malignancies complained of milder degree of pain. Zoeter patienta associated with malignancies were more frequently DNCB-negative and had decreased OKT3+ pan T cells, OKT4+ helper/inducer T cells as compared with control group, which suggest impaired cell mediated immunity in the former.

Malignant rhabdoid tumor (MRT) is a rare and highly aggressive neoplasm of infancy and childhood. Although it was originally described and most frequently reported in the kidney, it may occur in various extra-renal sites such as the liver, thymus, and soft tissue. In the last decade primary central nervous system (CNS) MRTs have been reported in both the supra- and infratentorial compartments. Patients with CNS MRT were generally below the age of two and reports in adults are extremely rare. This is a case of primary cerebellar MRT in a 24-year-old woman, who had presented with intermittent headache, vocal cord palsy, and cerebellar dysfunctions such as abnormal finger to nose test and tandem gait. By magnetic resonance imaging scan, a well-enhancing solid mass was demonstrated at the posterior fossa filling the 4th ventricle, which extended into the medulla and cervical cord via the foramen of Magendie. Histologically, the monotonous polygonal tumor cells were arranged in diffuse sheet with occasional hemorrhagic necrosis. The nuclei were vesicular and eccentrically located due to eosinophilic, PAS-positive, intracytoplasmic inclusions with prominent nucleoli. They were diffusely or focally immunoreactive for vimentin, neurofilament, cytokeratin, GFAP, synaptophysin, and smooth muscle actin, while epithelial membrane antigen and desmin were negative. Ultrastructurally, the polyhedral tumor cells were densely packed with primitive intercellular junctions. Scanty fibrillar intermediate filaments were intermingled with cellular organelles. Postoperatively, craniospinal irradiation and systemic chemotherapy have been done and she has been free of tumor recurrence during the 13 months' follow-up periods.

Clinical observation was made on the 16 patients of penile carcinoma admitted to the Department of Urology, Seoul National University Hospital during the period from September, 1967 to August, 1976 and the following results were obtained. 1. The incidence of penile carcinoma was 0.5% of total inpatients of urologic department and 3.5% of male genitourinary tumors. 2. Age distribution was between 29 and 78, snowing highest incidence at 50-59 years. 3. Clinical findings were; mass 77%, discharge 28%, ulcer 25%, bleeding 13%, and inguinal lymphadenopathy 50%. 4. The average duration of the symptoms on admission to hospital was 10 months with the highest incidence in 1 to 6 months. 5. The locations of the tumors were; preputial cavity 87%, confined to glans 6%, penile shaft involved 6%. 6. Treatments were made with partial amputation in 50%, partial amputation with inguinal lymphadenectomy in 37%, and biopsy in 13%.

It is known that the cardiovascular system is extremely sensitive to the effect of both exogenous and endogenous opiates. In rabbits, less than 1% of the usual morphine dose necessary to produce antinociception results in significant hypotension and bradycardia. The endozenous opiate, beta-endorphin, is stored along with pitulatary adrenocorticotorphin(ACTH), and the action of stressors seems to result in the release of both peptides. Therefore it seems likely that beta-endorphin is released during stress such as shock and that it might contribute to the hypotension. In order to probe this hypothesis, hypovolemic and endotoxin shock model were produced in rabbits. If these hemorrhage and endotoxin induced hypotension were mediated through the beta-endorphin release, the blockade of beta-endorphin should reverse such hypotension. Using the specific opiate antagonist, Naloxone-HCl, these hypotensions could be reversed and prevented as following results show, 1) As compared with the saline control, the hypovolemic shock experiment had a 36.49+/-14.44% increase in mean arterial pressure(MAP) within 2 to 3 minutes and the endotoxin shock had a 52.43+/-23.66% increase in MAP within 5 to 6 minutes after naloxone treatment (0.4mg/kg). 2) AS compared with the saline control, in both hypovolemic and endotoxin shock naloxone pretreatment(0.4mg/kg) could prevent the decrease of MAP significantly. 3) No significant difference were seen in heart rate between the control and both experimental groups. And plasma bets-endorphin was measured by radioimmunoassay(RIA), using beta-endorphin kit(Immunonucler corportion, Stillwater, Minnesota, USA) and Beckman 8,000 tau-Counter, in these shock model with following results. 1) Hemorrhage and endotoxin induced shock produced a significant increase in plasma beta-endorphin to about 3 times control and reversed by naloxone treatment(0.4mg/kg) significantly as compared with saline control. 2) AS compared with the saline control, in both hypovolemic and endotoxin experiments naloxone pretreatment(0.4mg/kg) could prevent the increase of plasma beta-endorphin significantly.

To evaluate the possible therapeutic effects of growth hormone and vitamin C on multiorgan failure, a rat model was developed for LPS-induced sepsis. Using this model, the effects of growth hormone and vitamin C on tissue damages, catalase and i-NOS activities, and MDA levels were examined in the lung and liver. The level of TNF-in plasm was also examined. Male, Sprague-Dawley rats were injected with LPS intraperitoneally then divided into 3 groups : positive controls injected with LPS only, the ones injected with growth hormone or vitamin C immediately after the LPS injections. The lung and the liver were then isolated, blood samples were collected at 24 or 48 hours after the LPS injection, then examined for histopathological and biochemical changes. The results obtained were as follows. 1. LPS induced sinusoid vasodilation and mild destruction of lobular structure in the liver. In the lung, alveolar structure appeared to be thickened and interstitial edema was observed. The levels of MDA in the liver and the lung was increased by LPS, while the activity of catalase was decreased. The activity of i-NOS of those tissues was also increased, which was more pronounced at 24 hr. The level of TNF-in plasm was increased by LPS 2. In the lung, vitamin C suppressed lymphocyte and neutrophil infiltration, alveolar wall thickening and interstitial edema. In the liver, vitamin C protected against the destruction of the lobular structure. The activity of catalase reduced by LPS was reversed partly by vitamin C. The activity of i-NOS enhanced by LPS was also reversed by vitamin C. The level of TNF-in plasm reduced in some animals by vitamin C, which however was not significant statistically (P<0.05). 3. Growth hormone showed similar protective effects against inflammation and damages in the liver and lung tissues. Growth hormone reversed partly the LPS effects on the level of MDA, the activity of catalase and i-NOS induction in the liver and the lung. Growth hormone reduced plasma level of TNF-alpha substantially, which contrasted from vitamin C. Besides this, overall protective effects of growth hormone against LPS-induced experimental sepsis were similar to those of vitamin C. From this results, the mechanism of growth hormone on suppression of LPS-induced tissue damage might be associated with production of antioxidative enzyme and suppression of plasma TNF level.

Congenital self-healing reticulohistiocytosis (CSHRH) is a rare Langerhans cell disorder usually showing spontaneous resolution within 3-4 months. By electron microscopy, the identification of Birbeck granules and laminated dense bodies in the infiltrated cells is mandatory for the diagnosis of CSHRH. However, in some reported cases, Birbeck granules could not be demonstrated and only cytoplasmic dense bodies were seen. If the lesion is more advanced, Birbeck granules are transformed to lysosomes, i.e., 'unique phagosomes', in which they are degraded. A 2-month-old Korean girl presented with congenital, numerous red-brown pigmented papules on the left side of trunk and upper extremity without systemic symptoms. A biopsy specimen demonstrated papillary dermis containing epidermotropic infiltrates of histiocytes with abundant eosinophilic cytoplasm. Some had kidney-shaped nuclei and PAS-positive cytoplasmic inclusions. Immunohistochemically, infiltrating cells expressed S-100 protein and ultrastructurally, no Birbeck granules but many dense laminated bodies and unique phagosomes were found. It was ten months since the skin lesions developed that they have started resolving.
