In mammal, lots of follicles start simultaneously their growth but only a few oocytes are ovulated in every sexual cycles. Most of matured and grown oocytes are destined to degenerate by atresia. However, the molecular and physiological mechanisms are not elucidated yet. The present study was designed to establish an induction method of follicular atresia with ketamine or pentobarbitone and evaluate the effect of these anesthetics on oocyte maturation and granulosa cell apoptosis of the mouse ovarian follicle. The percentages of degenerated oocyte and apoptotic granulosa cell in ketamine treated groups were significantly higher than that in controls (58.9% vs 33.5%, p<0.01, degeneration; 44.9% vs 26.6%, p<0.01, apotosis). Futhermore, it was revealed that the concentrations of progesterone in both groups were markedly higher than that in control. In conclusion, it is considered that ketamine induce an atresia as pentobarbitone, and may be useful for inducing follicular atresia.

Primary carcinoma arising in the diverticular wall of the urinary bladder is the most serious complication. The clinical importance is that the carcinoma is difficult to diagnose early, widespread at diagnosis and has poor prognosis. Recently, vigilant studies including bladder mapping reveal premalignant changes and carcinoma in situ adjacent to carcinoma and suggest these premalignant changes evolve to flank carcinoma. For early detection and improving the prognosis, be required through cystoscopic examination including diverticular wall and multiple punch biopsies as well as consecutive urine cytologic examination. Author report two cases of primary carcinoma arising in bladder diverticulum. One revealed carcinoma in situ accompanied with adjacent atypical hyperplasia in diverticula mucosa incidentally found at the pathologic examination on the divertiuclectomy specimen. The other case showed invasive transitional cell carcinoma(Grade IV, Stage D) of diverticulum. The two cases described suggest that vesical diverticulum should be removed into to with a good amount of surrounding bladder wall.

OBJECTIVE: The purposes of the present study were to investigate the effect of gamma-radiation on the expression of inhibin-alpha proteins and genes for inhibin alpha, betaA, and betain the ovary. METHODS: Immature mice were whole-body gamma-irradiated with 25% of a lethal dose. At time 0, 3, 6, 12, and 24 hours after the irradiation,the ovaries were collected and used for immunohistochemistry for inhibin-alpha, and RT_PCR for inhibin-alpha, betaA, and betaB. RESULTS: The expression of the immunoreactive inhibins-alpha was maintained at 12 hours post-irradiation and reduced thereafter. The expression of inhibin-alpha mRNA was significantly increased with the time after the irradiation. However there were no significant changes in the expression of betaA and betaB mRNAs. CONCLUSION: It might be thought that inhibin acts as one of the regulatory factors in the gamma-radiation-induced follicular atresia in mice

There are various complex formations between immunoglobulin and serum enzymes in the body. Of these, LD-Immunoglobulin complex is most common. It has reported that LD-IgG or LD-IgA complex existed in the serum of healthy person or many patients who have various clinical disorders. The clinical significance of complexes is not known, but it results in the increase of total LD activity and interference to the LD isoenzyme electrophoresis interpretation due to its anomalous pattern. We have reported a case of LD-Immunoglobulin complex in AILD(Angioimmunoblastic lymphadenopathy with dysproteinemia) with reference. The patient was admitted with fever, chills and cervical LN enlargement, in LN biopsy, diagnosed AILD, and during treatment expired by sepsis. Since admission, serum total LD activities were increased and serum LD isoenzyme EP showed that LD3-5 fractions was not separated in broad single band. Its pattern was due to LD-immunoglobulin complex, LD-bound immunoglobulin was IgG ,lamda. For the identification of immunoglobulin, we at first did serum protein immunoelectrophoresis. then stained the plate with tetrazolium dye for LD activity.

Malignant fibrous histiocytama is currently defined as a malignant primary bone tumor, and that may contain fibromatoua, xanthomatous, or histiocytic elementa, varing widely in the degree of anaplasia that is present. The principal lesions to be considered in the differential diagnoais of malignant fibrous histiocytoma are osteogenic sarcoma and fibrosarcoma. Malignant fibrous histiocytoma is more sensitive to chemotherapeutic ageata than are osteosarcama and fibrosarcama. In this paper 2 cases sre reported, including the one in which the tumor arose in a midahaft of the femur and the other one arosein the upper metaphyseal portion of the tibla.

"Background: In using the Double-lumen tube (DLT), knowing the minimum bronchial cuff volume (MCV) for an effective air-tight seal will be useful; to provide a collapse of the lung; and to avoid pressure damage. The aims of the present study are thus three-fold: to measure the MCV; to measure the diameter of left main bronchus (LMBD); and to prove any relationships between two parameters. METHODS: One hundred men and forty women who needed intubation of left-sided DLT were enrolled in this study. 37 Fr DLTs were used in male patients, and 35 Fr DLTs were used in female patients. We evaluated the MCV by air bubble method and measured the LMBD in chest PA. We also evaluated the pressure/volume characteristics of the bronchial cuffs by control inflator. RESULTS: 29 patients of 100 patients (29%) exhibited persistent air leakage in 2.5 ml cuff volume in male patients (group of MCV >2.5). On the contrary, 18 patients of 40 patients (45%) did not require any cuff volume in female patients (group of MCV 0). The mean LMBD were 13.23 1.45 mm in male and 11.09 0.96 mm in female. There were significant positive correlations between MCV and LMBD in both sex and their respective correlation coefficients were 0.264 (P=0.008) in male and 0.484 (P=0.002) in female. The equations of linear regression were: LMBD = 12.394 0.429xMCV in male, LMBD = 10.725 0.438xMCV in female. CONCLUSIONS: The MCV of the brochial cuffs in left-sided DLTs has significant relationships with the LMBD measured in chest PA.

Alpha-fetoprotein (AFP) is a well-known tumor marker for hepatocellular carcinoma, hepatoblastoma, and yolk sac tumors. There are several studies on AFP-producing tumors that arose from the gastrointestinal tract, pancreas, lung, kidney, and urachal tract. AFP-producing carcinoma of the gallbladder is extremely rare. We report a case of AFP-producing carcinoma of the gallbladder without liver involvement in a 58-year-old man with a gallstone, on which clinical, morphologic, and immunohistochemical studies were performed.
