The crude drug Aconite Root (bushi in Japanese) contains toxic compounds called bushi diester alkaloids(BDA), and the raw material with high BDA content has been considered suitable for processing into prepared bushi. Moreover, processing methods and an upper BDA content limit are prescribed in the 16th edition of Japanese Pharmacopoeia. In this study, we closely examined descriptions of high quality bushi in ancient herbal literature, and elucidated the relationship between bushi forms and BDA contents. The results showed that large-sized bushi with enlarged rootlets called “horns” (tsuno in Japanese) were considered higher quality, and the horns and the root tops (hozo in Japanese) were cut off when used as bushi. Meanwhile, chemical studies have shown that larger bushi contains less BDA, and the root tops and the horns contain more BDA than the root body. These results suggest that selecting larger roots and cutting off the more potent parts were processes for reducing BDA. Therefore we conclude that consistently less toxic bushi was considered a higher quality product in ancient times.

The present study was performed to investigate the effects of 120 km walking, 40 km a day for 3 successive days on the condition that taking rest and foods freely, upon physical functions for healthy male and female subjects. All measurements were enforced at postabsorptive state early in the morning for the 10 successive days including the days of walking. Blood pressure, heart rate, and body weight were measured every morning. Blood samplings enforced, too. Urine collections were enforced from first day to 7 th day. The results obtained were as follows;
1) There were no changes in heart rate, blood pressure, and body weight, which were measured early in the morning, before and after 120 km walking.
2) Serum GOT and GPT activities had little changes, while serum LDH, α-HBDH, and CK activities increased gradually after walking.
3) Serum CK-MB activities, which indicate myocardial injury, increased after walking, on the contrary CK-MB/CK ratio decreased. It was suggested that effects of 120km walking to myocardium were rather than slight ones.
4) In spite of the same sorce in which serum CK-MB and LDH-1 were resulted, both did'nt exhibit same patterns in serum.
5) Serum lipids decreased gradually after walking.
6) Urinary excretion of creatinine and uric acid increased after 120km walking especially.
7) If it is allowed to take sufficient foods and rest, 120km walking, 40km a day for 3 successive days, would not result in such a physical stress over the following days.

1) As to the degree of in heart rate upon 5 km running, in males, there were no differences between taurine administration group (M-group) and placebo administration group (P-group) . But in females, recordings in P-group were much larger than those of M-group.
2) As to the degree of increase in systolic blood pressure upon 5 km running, in males, no differences between both groups were observed, but in females, recordings in P-group were larger than those of M-group.
3) Both serum creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) activities did not recover to pre-exercise levels during 3 days after 5 km running in both groups of both sexes.
4) In the rate of CK-MB against CK, not only P-group of females had extraordinary high levels immediately after 5 km running, but also P-group of both sexes had higher levels on 3rd and 5th day after 5 km runnning than M-group.
5) In both sexes P-group was larger than M-group in the degree of increase in blood lactate and serum triglyceride levels.
6) As to the changes in serum total protein levels, in males, no differences between both groups were observed, but in females, P-group had extraordinary low levels on 1st day after 5 km running and maintained low levels during 5 days recovery.
7) As to the changes in both serum total fatty acids levels and the rate of unsaturated fatty acids against total fatty acids, no differences were observed between both groups of both sexes.
8) As to the degree of increase in plasma noradrenalin and adrenalin levels, in males, no differences between both groups were observed, but in females, recordings in M-group were larger than those of P-group.

Effects of taurine on the functions of the body and metabolism with 3km running upon taking a diet, which is constituted of lowest possible amount of carbohydrate and highest possible amount of fat and protein, were investigated in 25 male and female subjects of age thirties by double blind test method. The results were as follows
1) Taurine administration (T. A.) proved to inhibit the degree of increase in heart rate and increase the maximal degree of pulse pressure in response to 3 km running.
2) T. A. proved to inhibit the degree of increase in serum creatine kinase isozyme MB (CK-MB) activities and CK-MB/CK ratio.
3) T. A. proved to inhibit the decrease of serum total protein values immediately before running and in the following morning. Similar trends in terms of the particuler times were observed, too, in the case of the degree of decrease of serum triglycerides values.
4) T. A. seemed to accelerate the utilization of saturated fatty acids especially.
5) Three kilometer running seemed to increase in serum taurine concentrations from several hours after running to the morning immediately after running.

This report concerns a 62-year-old woman with Wegener's granulomatosis. She complained cough, macroscopic hematuria and oligulia. She had a consolidation without a cavity in the left upper lung field, massive proteinuria (2.5 g/day) and massive hematuria. The serum creatinine level was 2.5 mg/dl. The C-ANCA was positive. Renal biopsy revealed crescentic glomerulonephritis. She wa treated with prednisone and trimethoprim-sulfamethoxazole. The lung shadow, proteinuria and hematuria disappeared in one month. The C-ANCA titer also decreased. The use of trimethoprimsulfamethoxazole which may eliminate an infection as a cause to promote Wegener's granulomatosis should be actively included in the conventional treatment.

The development of clinically applicable scaffolds is important for the application of cell transplantation in various human diseases. The aims of this study are to evaluate fibrin glue in a novel protein replacement therapy using proliferative adipocytes and to develop a mouse model system to monitor the delivery of the transgene product into the blood and the fate of the transduced cells after transplantation. Proliferative adipocytes from mouse adipose tissue were transduced by a retroviral vector harboring the human lecithin-cholesterol acyltransferase (lcat) gene, and were subcutaneously transplanted into mice combined with fibrin glue. The lcat gene transduction efficiency and the subsequent secretion of the product in mouse adipocytes were enhanced using a protamine concentration of 500 microg/ml. Adipogenesis induction did not significantly affect the lcat gene-transduced cell survival after transplantation. Immunohistochemistry showed the ectopic enzyme production to persist for 28 days in the subcutaneously transplanted gene-transduced adipocytes. The increased viability of transplanted cells with fibrin glue was accompanied with the decrease in apoptotic cell death. The immunodetectable serum LCAT levels in mice implanted with the fibrin glue were comparable with those observed in mice implanted with Matrigel, indicating that the transplanted lcat gene-transduced adipocytes survived and functioned in the transplanted spaces with fibrin glue as well as with Matrigel for 28 days. Thus, this in vivo system using fibrin is expected to serve as a good model to further improve the transplanted cell/scaffold conditions for the stable and durable cell-based replacement of defective proteins in patients with LCAT deficiency.

The purpose of this case report was to report a rare case of pyogenic spondylodiscitis caused by Campylobacter fetus. A 37-year-old male presented with fever and low back pain. By lumbar magnetic resonance imaging (MRI), no abnormal finding was observed at the first presentation. However, low back pain was aggravated, and fever did not improve. Thus, lumbar MRI was repeated on the 26 day after the onset of symptoms, showing abnormal signals at vertebrae and disc spaces, and pyogenic spondylitis was diagnosed. The possibility of pyogenic spondylodiscitis should be taken into account if a patient presents with low back pain and fever, and areas of low signal intensity on a T1-weighted MRI should be carefully examined. When initial MRI does not reveal abnormal findings, repeated MRI after one or two weeks or, more favorably, immediate gadolinium enhancement MRI, are important for patients who have persistent low back pain and fever.
