In order to study the histogenesis of gastric carcinoma, and to find the correlationship between the gastric carcinoma and endocrine tumor of digestive tract, we performed immunoperoxidase staining for serotonin, somatostatin and gastrin respectively in the 34 cases of surgically resected gastric carcinoma. The results were as follows; 1) Endocrine cells were found in 26.5% (9/34) of the gastric adenocarcinoma, but in 58.6% (17/29) in the normal gastric mucosa near the cancer area. The occurrence of endocrine cells was less frequent in cancer than in the normal gastric mucosa. 2) Among the 15 cases of intestinal type adenocarcinoma, serotonin-positive cells were found in 2 cases, somatostatin-positive cells in 1 case and gastrin-positive cells in 1 case. Among 16 cases of diffuse type adenocarcinoma, gastrin-positive cells were found in 2 cases, and somatostatin-positive cells were found in 2 cases. 3) We concluded that, the endocrine cells are more frequently observed in the well differentiated gastric carcinoma than poorly differentiated carcinoma tissue. In summary, gastric carcinomas are supposed to arise from the totipotent stem cells of endoderm origin, and they have multidirectional property of differentiation into both endocrine and nonendocrine cells. Most of them differentiate into nonendocrine cells and only a few of them differentiate into endocrine cells.

To evaluate the utility of gene rearrangement analysis, eight cases of malignant lymphoma, one case of Hodgkin's disease, two cases of angioiminunoblastic lymphadenopathy (AILD) and two cases of non-specific lymphadenitis were studied by immunohistochemical and genetic analysis. Southern blot analysis was perfon-ned by a using vacuum transfer system and a biotin labelled probe. This method was faster, safer, and more convenient than conventional methods. Gene rearrangement study showed rearranged novel bands in five of six cases of B cell lymphoma, in all cases of T cell lymphoma, and in all cases of AILD. No rearrangement of the B cell receptor(BCR) or of the T cell receptor(TCR) was seen in Hodgkin's disease or in nonspecific lymphadenitis. These results suggest that gene rearrangement analysis of BCR and TCR is a recommended method for the diagnosis of clonality in lymphoproliferative disorders. It would allow pathologists to differentiate lymphoma from polyclonal lymphoid proliferation and to provide information for cell lineage.

Parathyroid carcinoma is a relatively rare endocrine tumor, accounting for approximately 1 to 5% of patients with primary hyperparathyroidism. Patients with parathyroid carcinomas are often symptomatic, have markedly elevated calcium levels, and have a palpable cervical mass. They are equally distributed between the sexes and usually present 10 years before their benign counterparts. The diagnosis is suspected when the tumor is large, parathyroid hormone levels are high, and a palpable mass is present in the neck. Parathyroid carcinoma is often misdiagnosed preoperatively, suspected intraoperatively, and only confirmed postoperatively. We experienced a case of hyperfunctioning parathyroid carcinoma in a 36 year old man, which was confirmed microscopically. The tumor showed: 1) capsular and blood vessel invasion; 2) frequent mitotic figures in the parenchymal cells; 3) a trabecular pattern, and 4) intervening thick fibrous bands. Immunohistochemical stain of p53 may be one of the useful methods in identifying malignancy of parathyroid gland.

A forty-nine-year-old woman with polycystic disease had a right nephrectomy for what was preoperatively thought to be a polycystic disease, but at surgery turned out to be a tumor based on frozen section. Microscopic examination revealed papillary type, renal cell carcinoma with classical features of adult polycystic kidneys. Radiologic findings revealed multiple cysts in the liver. The clinical recognition of a carcinoma developing in polycystic kidneys is often difficult because of the presence of preexisting large renal masses and occasional hematuria. Renal cell carcinoma should be thought of when confronted with abdominal pain or back pain, severe hematuria, sudden dysuria or a new renal mass occurring in a patient with polycystic kidneys.

Ichthyosis hystrix is a localized variant of Bullous Congenital Ichthyosiform Erythroderma by Broq, and also, localized form of Epidermolytic hyperkeratosis according to Frost and Van Scott's classification of ichthyosi-form dermatoses. Clinically it is generally considered to be widespread systematized epidermal nevus, and demonstrating an autosomal dominant pattem of inheritance, and characterized by verrucous scale at or shortly after birth with particular involve- ment of flexural areas. A case of 21 year old girl with ichthyosis hystrix was reported, The skin lesion showed multiple rice to pea sized linear verrucous papules on left forearm, neck, axilla and upper chest. The skin biopsy was done, the finding shows remarked laminated hyperkeratosis, acanthosis, papillomatosis, and vacuoliization on malpighian layer. Diagnosis was confirmed by clinicaI apperance and histopathologicaI finding. The method of treatment is 0. 05% Vitamin A acid ointment application and show marked improvement.

Carp which receive intraperitoneal injections of sodium alginate show a high survival rate after being challenged with Edwardsiella tarda. To elucidate the immunoenhancement by sodium alginate, its effects on the non-specific defense system of carp were investigated. Sodium alginate had little influence either on the activity of the alternative complement pathway or on the phagocytic and respiratory burst activities of head kidney phagocytes (HKP), yet it greatly enhanced the migration of HKP to the peritoneal cavity (the site of injection) and concurrently elevated their phagocytic activity. The number of phagocytes mobilized by sodium alginate was 2 to 50 times greater than that by the well-known peritoneal exudate cell-eliciting agents when injected at the same dose. Accordingly, it is highly probable that the early elimination of challenge bacteria by such mobilized and activated phagocytes was responsible for the high survival rate of the alginateinjected fish. In chemotaxis assays, it was revealed that sodium alginate stimulated sorne leukocyte subpopulation (s) within the peritoneal cavity to produce and/or secrete chemotactic factor (s), while concurrently enhancing the sensitivity of HKP to the factor (s).

Acrokeratosis verruciformis is a familial disease characterized by indolent papules resembIing flat warts on the backs of the hands and feet with lesser involvement of volar surfaces, wrists, and ankles. A cas of 42 years old female with acrokeratosis verruciformis is reported. The skin lesions of this patient showed numerous rice to pea sized, flat-topped, round or polygonal, warty papules on the dorsal aspects of the hands and feet and also, pitted keratolysis on both volar surface of the hands. The hitologic findings were those of features of acrokeratosis verruciformis, i.e. the epidermis shows marked hyperkeratosis with slight acanthosis and papillomatosis and circumscribed elevations of the epidermis resembling church spires characteristically.
