We attempted an integrated assessment of male infetility by combining multiple parameters of semen and serum, and tried to select patients requireing intracytocplasmic sperm injection (ICSI). Significant correlations were demonstrated between the rate of fertilization by human in vitro fertilization (IVF) and five parameters, consisting of sperm concentration, a mortility and a proportion of morphologically normal sperm in semen, a rate of fertilization with the hamster test, and the serum concentration of FSH (R-square=0.627). According to the results of these five parameters, a male factor index (MFI) was calculated and relations between MFI and IVF outcomes were further analyzed. There were significant differences among three groups of patients with MFI of 0, 1-2 and 3-5 (20, 95 and 431 cycles, respectively) in the rates of fertilization (26.5, 51.3 and 65.2 %, respectively), embryo transfer (30, 78 and 92.6%, respectively), and ongoing pregnancy (0, 18 and 28.3%, respectively). The rate of abortion was significantly higher in patients with MFI 0 than in ones with MFI 1-5 (100 and 19 %, respectively). Fiftyfour cycles of ICSI were performed in patients with MFI 0 and significant improvement was obtained in the rates of fertilization, embryo transfer, ongoing pregnancy and abortion (63.0, 98, 26 and 6.7%, respectively), compared with IVF outcomes in patients with MFI 0. The study has shown that MFI is useful to predict IVF outcomes and that patients with MFI 0 should be treated by ICSI.

The relationship between the storage period of red blood cells (RBC) and anaerobic metabolism in recipient rats was investigated by transfusing stored blood (Hct 33 %, 20 ml/kg) into Sprague-Dawley rats in a state of hemorrhagic shock. Samples of transfused blood with different storage periods were used, before storage "O-w" group (n = 17), one week of storage "1-w" group (n = 10) and two weeks of storage "2-w" group (n = 9). Plasma lactates in the recipient rats 15 min after bleeding were significantly elevated from approximately 11 to 19mg/dl (p<0.01). The lactate values as long as 95 min after RBC transfusion in the 0-w group were lower than those at 15 min after bleeding (# : p<0.05). Plasma lactates at 35 min and 65 min after RBC transfusion in the 1-w and 2-w groups were significantly decreased, but, reincreased at 95 min after RBC transfusion as high as those at 15 min after bleeding. There was a positive correlation between the filtering pressure, which indicates the deformability of transfused RBC, and the plasma lactate in recipient rats at 95 min after transfusion (R=0.313, p=0.004). The author concludes that the transfusion of RBC stored for more than 1 week prolongs anaerobic metabolism in animals with hemorrhagic shock.

We studied the geographic correlation between nutrient consumption and the gastric cancer mortality across the five Public Health Center districts (Ninohe, Iwate; Yokote, Akita; Katsushika-kita, Tokyo; Saku, Nagano ; Ishikawa, Okinawa). In the winter of 1989-1991, three-days weighed food records were collected from 207 volunteered men and 165 spouses of the men sampled from the five districts. The average daily consumption of 16 selected nutrients were computed, and the correlation of these values with the age-adjusted mortality rates from gastric cancer were investigated. Partial rank correlation coefficients adjusted for sex were 0.6293, 0.5354, -0.8926, -0.5775, -0.4542 for thiamin, sodium, carotene, calcium, retinol, respectively. Among these nutrients, the percentage contribution of the interpopulation to total variance for sodium intake was found to be relatively great. These results suggest that although geographical variation in gastric cancer mortality in Japan might be accounted for by the regional differences in consumption of several nutrients, this nutrient-gastric cancer association may be more likely for sodium than for other nutrients.

To investigate the effects of aging on suicide mortality and the significance of socioeconomical factors as the modifiers of the aging effect, a cohort analysis and a cohort analysis-based ecologic study across 47 prefectures were conducted using the long-term vital statistics data in Japan. The increment in suicide mortality with aging substantially differed by birth cohort even within an identical age class, revealing that the relationship of aging to suicide mortality could be largely affected by the contemporary socioeconomical conditions. In almost all the birth cohorts, the greatest suicide increase with aging were noted for the adolescence (Age : 15 to 25). The results of the ecologic study on suicide mortality changes between 1990 and 1995 suggested that family composition, health status and the condition of medical services, and educational environment may play key roles as the modifiers of the aging effects on suicide mortality changes during the specific stages of the aging process. These results may provide some guidelines for the embodiment of improvement of mental condition and reduction of suicide in a Japanese population.

The inhibition of inhalational anesthetics to tracheal smooth muscle contraction induced by vagal stimulation was studied in vivo. Twelve adult beagle dogs were anesthetized with pentobarbital and vecuronium, and mechanically ventilated. The isometric contraction force of opened tracheal smooth muscle was measured by an electric transducer. The contraction was induced by the electrical vagal stimulation (20 Hz, 30 V, 2 msec, n=12) or the arterial infusion of acetylcholine (0.1μg/kg, n=6) during inhalation of halothane, isoflurane and sevoflurane (0.75 and 1.5 minimum alveolar concentration : MAC). The tension of tracheal muscle increased to 150〜160 % without inhalation of anesthetics. However, the increases were significantly inhibited to 115 ± 5%, 127 ± 7% and 119 ± 7 % during inhalation of halothane, isoflurane and sevoflurane (1.5 MAC, p<0.05), respectively. Isoflurane revealed weaker inhibition than halothane during vagal stimulation (p<0.05). All the anesthetics (1.5MAC) significantly depressed the tracheal contraction induced by acetylcholine infusion (p<0.05), in which there was no difference among the three anesthetics. In conclusion, sevoflurane has equally potent inhibitory effect as halothane against tracheal contraction induced by the vagal stimulation or the acetylcholine infusion.

A 32-year-old woman developed diplopia and dizziness several days after an upper respiratory tract infection. On admission, bilateral blepharoptosis, disturbance of ocular movements mimicking bilateral internuclear ophthalmoplegia, ataxia and areflexia were noted. CSF protein level was normal. Serum virus titers did not show any significant changes. Anti-GQ1b and anti-GT1b ganglioside antibodies were positive. Brain CT and MRI were normal. H wave was not elicited in nerve conduction study. She was diagnosed as suffering from Fisher's syndrome. Although her ocular motility dysfunction closely resembled internuclear ophthalmolegia, no proof of damage to the medial longitudinal fasciculus was obtained as shown by the normal findings in MRI. Meanwhile, disappearance and subsequent re-appearance of H wave during the clinical course rather suggested the peripheral origin of her ocular disturbance. Pseudo-internnuclear ophthalmoplegia has been reported in myasthenia gravis, Guillain-Barre syndrome and surgical pare is of the medial rectus muscle, indicating that lesions of the peripheral nerve and muscle simulate what has previously been considered a specific brainstem sign. Dissociated nystagmus in this ophthalmoplegia can also be explained by an adaptiveprocess theory. Namely, any attempt to increase the innervation to a weakened muscle in one eye is thought to be accompanied by a commensurate increase in innervation to the yoke muscle in the other eye, giving rise to saccadic overshoot followed by backward postsaccadic drift.

Herpes simplex encephalitis is well known as an acute type of limbic encephalitis, and a paraneoplastic syndrome is also known as a subacute and progressive type of limbic encephalitis. However, we experienced a 25-yearold woman in whom the both types of limbic encephalitis were excluded, and the diagnosis of non-herpetic acute limbic encephalitis (NHALE) was established. The lesion was confined to medial parts of the temporal lobes, namely hippocampi, amygdaloid nuclei, parahippocampal gyri and fusiform gyri which showed abnormal signal intensities on MRI. In this patient, fever was the first manifestation similar to the usual encephalitis, but consciousness was clear and memory impairment was remarkable from the initial stage of the illness, which remained about one and a half years later as the typical feature of amnesia. Totally 24 cases of NHALE including our case have been reported. In all the cases, the immediate recall and the remote memory were intact, and only the recent memory was impaired, which is characteristic of the amnestic syndrome due to damage to the hippocampi. Among the 24 cases of NHALE, 46 per cent did not have fever, and 38 per cent did not show lowered levels of consciousness, which indicate that the diagnosis of encephalitis would not always easy in the initial stage of the illness.
