Abstract | Three patients with severe halothane-induced liver injury are described. All patients received halothane anesthesia twice within a short period. High fever and jaundice were noticed soon after the second operation. The prothrombin time was less than 40%, and eosinophilia was greater than 7% prior to these symptoms. Other causes of liver injury were excluded. Diagnostic criteria for halothane-induced liver injury are proposed. |

Abstract | The effect of coenzyme Q10 (Co Q10) was examined on the survival time and lipid peroxidation of adriamycin (ADM)-treated ICR mice. Co Q10 showed a protective effect against a subacute toxicity in mice induced by two intraperitoneal administrations of ADM (15 mg/kg). The group treated orally with 10 mg/kg of Co Q10 showed the longest survival time of all the groups studied (16.81 +/- 10.29 days, mean +/- S.D.) and a significantly longer survival time (p less than 0.001) than the ADM-alone group (7.48 +/- 1.99 days). The inhibitory effect of Co Q10 on the plasma and tissue lipid peroxidation levels did not correlate with the effect of prolonging the survival time of mice. Co Q10 tended to inhibit rises in plasma and liver lipid peroxidation levels induced by ADM administration, but there was no statistically significant difference between treatments. There was a statistically significant different inhibitory effect in the kidney lipid peroxidation levels, but was not in those of the heart. |

Abstract | Childhood leukemia, especially acute lymphocytic leukemia, can now be completely cured by a multimodality approach in one out of every two patients. Since prolonged maintenance therapy with anti-cancer agents for three years is required for complete cure, a significant problem during this course of treatment is death due to secondary infection. Those with childhood leukemia receiving anti-cancer chemotherapy who became secondarily injected with chicken pox can now be treated successfully with interferon in the four cases reported here. Chicken pox was cured even while one of them was in relapse. Therefore, it can be said that a bright prospect, namely interferon, is on the horizon in the treatment of secondary viral diseases associated with acute leukemia. |

Abstract | The whole body including extended processes of Ito's fat-storing cells was observed by scanning electron microscopy in rat liver injured with lithocholic acid (LCA). Necrotic foci developed in the midlobular zone 48 h after LCA administration. Demonstration of Ito cell bodies around the foci was probably facilitated by easy detachment of hepatocytes from Ito cells. The body and the processes were located mainly between the sinusoidal endothelium and hepatocytes; sometimes they were between hepatocytes. Ito cells often were proximate to collagen fiber bundles and sometimes were attached to them. The cell body was flatly round or elliptic, 7 to 12 micron in diameter. Its surface was finely undulated with microvillous projections about 0.1 micron in length. Branching patterns of the processes resembled a fern-leaf mantling the sinusoidal endothelium. The trunks of the processes were about 2 micron in diameter and 20-30 micron in length. These processes tapered, branching into thinner processes, with the most peripheral being 0.1 micron in diameter. Ito cells and their branching processes likely strengthen sinusoidal walls and control blood flow in the sinusoids. |

Abstract | The effect of cecectomy on food intake and defecation was studied in Wistar rats fed ad libitum or under restriction. Food intake, fecal output, dry matter and water content of feces, and numbers of scybala increased significantly in both groups of cecectomized rats. The weight of scybala and their dry matter and water content also increased after cecectomy. Water intake did not change significantly. It was considered that changes in the parameters after cecectomy may have resulted from lowered digestion and enhancement of propulsive activity in the gastrointestinal tract. |

Abstract | In guinea pigs whose pelvic nerves were bilaterally sectioned, afferent stimulation of rectoanal branches of the pelvic nerve (PAS) could produce an intense contraction in the rectum similar to propulsive contractions elicited during defecation. The mechanism of this reflex was analyzed. Rectal contraction by PAS was abolished after transecting the spinal cord at T13 or sectioning the lumbar splanchnic nerves (LSN) or lumbar colonic nerves (LCN), but was unaffected by severing the intermesenteric and hypogastric nerves. Rectal contraction induced by PAS was abolished peripherally by atropine, guanethidine or yohimbine, while propranolol had no affect. Yohimbine antagonized the inhibitory effect of LSN or LCN stimulation on atropine-sensitive rectal contractions. It may, therefore, be concluded that PAS blocks the inhibition, by LCN efferents acting through alpha-adrenoreceptors, of cholinergic neurons in the myenteric plexus, thus facilitating recto-rectal propulsive contractions initiated by the defecation reflex. |

Abstract | Experimental hepatocellular carcinoma (HCC) in rats did not take up intravenously administered indocyanine green (ICG) and trypan blue, while surrounding tissue did. The lack of ICG uptake was also observed by peritoneoscopy in patients with HCC. The contrast between ICG-stained cirrhotic nodules and HCC tumors was intensified with infrared photography. Non-uptake of dyes by HCC cells may enable discrimination between tumors and normal cells. |

Abstract | Rat Kupffer cells were observed and counted under a scanning electron microscope after a single dose of zymosan. The cell number increased after 24 h and reached 2 times the control after 72 h. The percentage of cells presenting numerous microvilli increased from 24% to 86% over the same period. Carbon clearance, a measure of phagocytic activity, decreased temporarily, regained control values after 12 h, and attained a 4-fold elevation at 72 h. Phagocytic activity paralleled Kupffer cell number, but increased more relatively. This result probably reflected activation of resident Kupffer cells as noted by numerous thick microvilli. |

Abstract | Using C3H/He mice, the antitumor effect of lipopolysaccharide (LPS) alone and in combination with Lentinan extracted from Lentinus edodes was studied. The influence of LPS on cellular immunity and the antitumor effect of the tumor necrosis factor (TNF) were also examined. LPS, which was administered into mice with tumor, induced hemorrhagic necrosis of the tumor within 48 h, demonstrating a high antitumor effect. When LPS was used in combination with Lentinan, the tumor growth was significantly inhibited as compared to that in the control mice. The combination of LPS and Lentinan prevented a decrease in the delayed type hypersensitivity in tumor bearing mice. Application of rabbit serum containing TNF resulted in hemorrhagic necrosis of the tumor within 48 h, as with LPS. |

Abstract | A progesterone receptor (PR) in human uterine cervical nuclei was demonstrated by a nuclear exchange assay using a synthetic progestin, promegestone (R5020) as a radio-labeled ligand. Total exchange of previously bound progesterone with R5020 was achieved by incubation at 0 degree C for 3 h. A 0.6 M KCl solution was used to extract the nuclear PR in uterine cervical tissue, and the dextran coated charcoal (DCC) method was used to separate the free [3H] R5020 from the bound form. Scatchard plots of nuclear PR binding showed two components with dissociation constants of Kd = 2.3 X 10(-10) and 4.6 X 10(-9) M. Three histological regions of the uterine cervix was studied as to their nuclear PR contents throughout the menstrual cycle. In the follicular phase, the connective tissue (CT) had the highest PR concentration (658.9 fmole/mg DNA), followed by the columnar epithelium (CE) (253.6 fmole/mg DNA), and the squamous epithelium (SE) (184.7 fmole/mg DNA). In the luteal phase, there was no significant difference among the three regions. Comparing these phases of cycle revealed that the CT had higher PR contents in the follicular phase than in the luteal phase, but no such difference was found in the CE or SE. These three regions had the same Kd value in both phases. |

Abstract | An enzyme-linked immunosorbent assay (ELISA) for the purpose of detecting the albumin receptor on hepatitis B virus surface antigen (HBsAg) particles was developed. Patient sera with moderate to high receptor values demonstrated significant correlations with serum DNA-polymerase activity (p less than 0.005), but not with HBeAg titer. Within one year of the study of 47 HBeAg-positive patients, only in the group of 12 patients with the moderately high values and 9 with low values, did 2 (16.7%) and 6 cases (66.7%) sero-convert, respectively. These results suggest that the albumin receptor might be a useful marker of HBsAg-positive patients. |
