    Adult worms of Dirofilaria immitis were found in the lateral ventricles of the brain of a dog suspected to be rabid. Such case as this seems to be very rare, though there is a report on the invasion. of these worms into the hepatic vein. The symptoms, anatomico-and histopathological findings are as follows:
    1) Symptoms. The dog showed the symptoms of canine filariasis consisting of nervous symptoms of unknown origin, such as slight paralysis of the posterior half of the body, a few days before death and a symptom similar to epilepsy on the day of death.
    2) Observations at autopsy. Anatomicopathologidal findings were not unusual in all the organs, except the brain and heart. The heart harbored about 40 worms of D. immitis in the right atrium. In the brain, a small spot of hemorrhage was found on the surface of the left piriform lobe, through which D. immitis got into the lateral ventricles. There was a large focus of hemorrhage near the site of invasion.
    3) Histopathological findings. Microscopic examination revealed destruction, softening, and remarkable hemorrhage of the tissues. Glial-cell proliferation and perivascular cell infiltration were found around the tissues destroyed by D.immitis. No infiltration of eosinophil cells was observed.

    It is well known that arsenicals are very effective adulticides among the chemotherapeutic agents for canine filariasis. However, they often cause emesis or nausea. Promazine hydrochloride and chlorpromazine hydrochloride are phenothiazine derivatives known as medicines causing artificial hibernation they are effective in preventing emesis and nausea. With this knowledge, the authors conducted the present experiments.
    Three different preparations were injected:
    (1) arsenical (0.75-1.00mg As/kg of dichlorophenarsin hdrochloride) only, (2) mixture of the arsenical (the same amount as above) and promazine hydrochloride (0.5-1.0mg/kg), and (3) mixture of the arsenical (the same amount as above) and chlorpromazine hydrochloride 1.0mg/kg. Compared with (1), the other two were markedly effective in preventing emesis and nausea. Dogs administered with these preparations retained normal appetite and vitality, proving the desirability of using promazine hydrochloride and chlorpromazine hydrochloride with arsenical. There was no significant difference in results of experiment between promazine hydrochloride and chlorpromazine hydrochloride when used with the arsenical.
    Additional experiments were conducted with the lethal dose (4.0mg As/kg) of arsenical. Some dogs were administered with the arsenical and promazine hydrochloride (2.0and 5.0mg/kg), and others with the arsenical and chlorpromazine hydrochloride (5.0mg/kg). As a result, the former dogs died, while the latter survived. Reactions of shock produced by the lethal dose of arsenical were dramatically averted by chlorpromazine hydrochloride (5.0mg/kg) and the dogs maintained their appetite and vitality.

    A survey was previously conducted of bacterial contamination and freshness of market ham and sausage in Hiroshima City. Furthermore, the same survey was carried out on these products during the manufacturing process in a plant. The results of the survey are as follows.
    1. The numbers of surviving bacteria per gram were 2, 500-∞ in ham and 3, 600-86, 000 in sausage. No coliform bacteria, however, were found from either food. The amounts of volatile basic nitrogen per 100 grams were 5. 60-14. 56 mg in ham and sausage. The amounts of NO2 were 2.99-13.80 ppm in ham and 1.64-5.91 ppm in sausage.
    2. From the results of examination of bacterial contamination during the manufacturing process, it is supposed that the number of coliform organisms increased as the process progressed, but was reduced to zero during the process of smoking and boiling. Although the organisms other than coliform bacteria showed the same tendency, a number of organisms survived after the process of smoking and boiling. The amount of volatile basic nitrogen increased as the process progressed (9.51-15.53 mg in ham and 8.68-16.10mg in sausage).

    Since 1955, field surveys have been conducted by this regional laboratory on the state of nutrition of dairy cows. As a part of these surveys, vitamin C levels in the blood and milk were determined, by the DNP method, in pure and hybrid Holsteins and pure Jerseys kept in crop and dairy farms in Niigata and Nagano Prefectures.
    The average value of blood levels was 0.490mg/dl in pure and hybrid Holsteins in Niigata Prefecture, 0.657mg/dl in Jerseys in Nagano Prefecture, and 0.637mg/dl in cows kept in the Nagano Breeding Stock Farm, Ministry of Agriculture and Forestry. In cows kept by crop farms in Niigata and Nagano Prefectures, no seasonal changes were present in blood levels, but negative correlations were observed, though a little, among blood sugar, serum protein, age, and blood level. In those kept by the Nagano Breeding Stock Farm, however, where feeding conditions and the circumstances under which examinations were performed were perfectly the same with those for the foregoing cows, the blood level showed seasonal changes and very distinct correlations with blood sugar and other factors, being high in winter and spring and low in summer. In short, there was a tendency of high blood sugar and low vitamin C level among them.In no areas of both prefectures, blood level of vitamin C was related to reproductive disorders, acetone in the urine, sugar in the urine, results of Gross test, yield of milk, and feedstuffs.
    It is assumed that the change of vitamin C level is influenced more deeply by the movement of the whole body than by any individual factor, as vitamin C level varies easily by stress.
    The average value of milk levels was 2.073mg/dl in the pure and hybrid Holsteins and 2.856mg/dl in the Jerseys, showing no correlations with blood levels.According to the results of examinations in the Nagano Breeding Stock Farm, there was a tendency that milk levels were high in winter and spring and low in summer, as well as blood levels. Milk levels of mastitic milk samples, except thoe showing separation of the components, were not so conspicuously different from those of normal milk samples and revealed no correlations with leukocyte counts in the milk.
