BACKGROUND: As a result of exposure to human leukocyte antigen(HLA) by pregnancy, blood transfusion and previous organ transplantation, many patients awaiting renal transplantation can develop HLA antibodies. The level of HLA sensitization is determined by PRA(panel reactive antibody) test using a lymphocyte panel from HLA phenotyped selected donors. In Korea, PRA tests have not been performed routinely for organ transplantations. and there is no available data about HLA sensitization in renal transplantation. METHODS: PRA test was done in 136 sera of chronic renal failure(CRF) patients receiving dialysis (hemodialysis 108, peritoneal dialysis 28) by NIH standard microlymphocytotoxicity method with a frozen lymphocytes panel from 36 HLA-typed donors. PRA positive sera were re-tested after dithiothreitol(DTT) treatment and analyzed for HLA antibody specificities. RESULTS: Thirty five out of 136 sera(25.7%) showed positive PRA values in HLA antibody screening test. The PRA(%) values of the 35 positive sera were distributed into 1-10%(n=8), 10-20%(n=7), 20-50%(n=12) and 50%-100%(n=8). respectively. After DTT treatment, the change of PRA reactivity was divided into three groups. The PRA values of Group A(22 sera: 63%) showed no change, Group B(7 sera: 20%) declined, and Group C(6 sera. 17%) completely disappeared after DTT treatment. The specificities of HLA antibodies were identified in 19 out of 35 sera(54%). The success rate in defining antibody specificities was 0 at PRA values of 1-10% and 70-100%, and high at PRA values of 20-70%. CONCLUSION: We observed that about a quarter of CRF patients have developed HLA antibodies of immunoglobulin class-IgG, mixed IgG and IgM, and IgM HLA antibody in decreasing order of frequency.

We present a 37-year-old male who was found to had mas within the bronchus. This patients was admitted for the evaluation of cough. Chest CT scan showed endobronchial mass in the bifurcation of LUL and LLL bronchus. The left lower lobe was atelectatic. Lobectomy of the left lower lobe was done. On opening of the bronchus, there was a 2x1x1 cm sized endobronchial mass. Histologically, the mass was smooth muscle tumor composed of densely packed eosinophilic spindle cells in interlacing bundles with pale elongated nuclei covered by bronchial epithelium. On immunohistochemical staining, the tumor cells were positive for desmin. Ultrastructurally, the tumor cells exhibited numberous cytoplasmic microfilaments with focal densities, pinocytotic vesicles, and a thick basal lamina.

Carcinoid is a tumor that primarily affects the intestinal tract, which arises from entero-chromaffin cells. Rectal carcinoid tumor is a relatively rare neoplasm originated in Kul-chitszky cell and clinicians have the difficulties in predicting their malignant potential and in proper treatment. These cells are found to increase in the distal small intestine, are common in the appendix, and then decrease within the mucosa of the colon from cecum to rectum. In the cumulative world literature, the incidence of carcinoids of rectum is slightly higher than 10 percent. All of these tumors are within reach of the rigid procto-sigmoidoscope, most being located between 4 and 13 cm from the anal verge. Eighty five percent are found on the anterior and lateral walls. The tumors are usually submucosal and light yellowish or reddish color. The vast majority of rectal carcinoid tumors are be-nign, which can be treated by local excision safely. Lesions larger than 2 cm and invading the muscular wall of the rectum should be considered malignant, which are treated by more radical surgery such as abdominoperitoneal resection. We experienced a case of rectal carcinoid tumor, which was excised by endoscopic polypectomy, so we present this case with a review of relevant literatures.

This study was performed to investigate the effect of octreotide on the contractility of rat vas deferens. The -smooth muscle strips isolated from the prostatic portion were myographied in isolated organ bath. Electric -field stimulation (monophasic square wave, duration : 1. mSec, voltage : 50 V, frequency : 5 Hz or 30 Hz, train : 10 Sec) produced reproducible contraction. The contraction was composed of two component, first phasic component (FPC) and second tonicc component (STC).. These contractions were abolished by -tetrodotoxin (1 microM). Octreotide inhibited the field stimulation induced contractions both FPC and STC concentration- dependently. The FPC was decreased by a desentization of purinergic receptor by pretreatment of mATP, and the STC was decreased by pr,,creatment of reserpine (3 mg/kg, EP) 24 hours before experiments. Octreotide reduced the field stimulation induced contraction in the presence of mATP and of reserpinized muscle strips. The inhibitory effect of octreotide was more potent at 5 Hz than at 30 Hz. Octreotide did not affect basal ton and exogenous norepinephrine- or ATP-induced contraction. These results suggest that octreotide inhibit the contractility of the isolated rat vas deferens by inhibition of the release of neurotransmitters, both ATP and norepinephrine from adrenergic nerve terminal.
