The purpose of this study was to observe the effect of training on morphological properties in the collagen fibers of tendons. Wistar strain rats at 7 weeks old were assigned to high speed endurance (H), moderate speed endurance (M), jump training (J) and control (C) groups. The amount of exercise for H group (speed at 30m/min for 60 minutes) and M group (speed at 17m/min for 75 minutes) was equalized according to the amount of oxygen consumed during training. As for the anaerobic training (J group), rats made high jumping form the standing position, wearing jacket with 50% of body weight, 50 times/day, which lasted for 4-5 minutes. The training period was designed for 5 days per week for 16 weeks.
The follwing is a summary of the results obtained:
1) Increases in fiber areas of both Slow-Twitch (ST) and Fast-Twitch (FT) fibers were observed in the H, M and J groups. The ST fiber area of H group was significantly larger than that of C group. Significant increase in FT fiber area was observed in both M and J groups.
2) Hypertrophy of collagen fiber in gastrocnemius muscle tendon was observed in Hand M groups; especially, M group showed much larger increase than H group. It tended to be greater for J group as compared with C group.
3) Collagen fiber area and diameter of tendon in plantar muscle were slightly larger for H and M groups relative to C group, but these differences were not significant.
These results suggested that both types of aerobic training induced hypertrophy in the collagen fibers of the tendons and increased the tensile strength; especially, the group which trained longer hours induced the higher effect.

We report a patient with hemifacial spasm in whom daijokito was effective. The patient was a 57-year-old woman who visited our clinic for treatment of fatty liver and asthma. She had been suffering from left blepharospasm and paroxysmal twitching movement of the left lower jaw in stressful situations during the 2 years prior to her first visit to us. After we prescribed daijokito because of her pot belly, she had no more asthma attacks and her left facial spasm improved. Seven months later, we added inchinko to daijokito for her liver damage. When we followed the test results of her clinical survey for two years, we found that her weight had decreased and liver function was improved after starting this dosage. We diagnosed her paroxysmal involuntary twitching on the left side of the face as hemifacial spasm, because these symptoms were unilateral. We regard that her hemifacial spasm was improved with relaxation, anticonvulsants, and the antianxiety action of daijokito.

We report a patient with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL) in whom saikanto was effective against pleural effusion induced by dasatinib, which is a second-generation tyrosine kinase inhibitor. The patient was a 43-year-old female. After she was diagnosed with Ph+ALL, she received imatinib and other chemotherapy. One year later, she started to receive dasatinib because of imatinib intolerance (vomiting and diarrhea). After about seven months of taking dasatinib, she experienced chest/back pain and a cough; at that time her chest x-ray showed right-sided pleural effusion. She consulted our clinic three months later, for treatment of the hydrothorax that frequently recurred. We prescribed saikanto because she presented with epigastric tenderness diagnosed as shokekkyo, and the pleural effusion and clinical symptoms improved remarkably. Because of the good clinical course in this case, we consider that the decrease of pleural effusion was caused mainly by the immunoregulatory and anti-inflammatory activities of saikanto in addition to its activities to alleviate fluid retention.

Aortoduodenal fistula is rare complication of nonoperative abdominal aortic aneurysm. We successfully treated a case of primary aortoenteric fistula associated with Behcet's Disease with two surgical intervention. The patient was 41 years old man. He admitted to our hospital because of severe shock due to enormous gastrointestinal hemorrhage. Emergency laparotomy revealed the inflammatory abdominalaneurysm ruptured into the duodenum. As the saccular aneurysm was densely adherent with duodenum and retoroperitoneum, graft replacement was abandoned. Primary closure of the perforated area of duodenum and the neck of aneurysm were performed. Axillofemoral bypass restored blood flow of the lower extremities. Three month after the operation, aortoduodenal fistula recurred. On the second operation, abdominal aorta was divided through retroperitoneal approach. However, primary closure of the enteric perforation with graft replacement of the aorta is considered as the first choice of the surgical treatment for aortoenteric fistula. In a case of difficult condition such as this patient with severe shock or retroperitoneal fibrosis, repair of the duodenum wall and division of the abdominal aorta with axillofemoral bypass is an alternative method of choice.

Case reports of drug-induced liver injury caused by Kampo medicines are on the rise, but most of them are noted for related symptoms such as jaundice. Usually, severe liver injury is detected by chance upon routine medical checkup. Recently, we noted 3 cases of suspected drug-induced liver injury caused by orengedokuto, saikokeishikankyoto and bofutsushosan. In these 3 cases, maximum ALT was under 100 IU/l and no symptoms related to liver injury were observed. Early detection by blood test was useful, and appropriate treatment quickly improved and normalized the abnormal values associated with liver injury. We should always be alert for drug-induced liver injury caused by Kampo medicines, especially when prescribing formulations that include Scutellariae Radix. We also emphasize the importance of scheduling blood tests when prescribing these formulations.
