We investigated whether preference for sucrose solution changes after exercise and whether the change influences post-exercise recovery of body fluid and glycogen. Rats were individually housed in cages equipped with 2 bottles containing water and either a 0.4%, 2%, 4 % or 8 % sucrose solution. The rats had free access to the water and sucrose solution for 6 h on both the day before (Pre) and the day of 2 h treadmill exercise (Ex). Fluid intake was measured. We also measured tissue weight, tissue water and tissue glycogen after 6 h recovery. Compared to Pre, voluntary fluid intake on Ex significantly decreased for 2 % and 4 % solutions, whereas it did not change for 0.4% and 8 %. After 6h of fluid ingestion, the content of tissue water and glycogen was highest for 8 % among the solutions. These results demonstrate that 8 % was effective in rehydration and tissue glycogen recovery after exercise, since its voluntary intake did not decrease after exercise.

To elucidate the phenomenon of central fatigue, we investigated the changes in the plasma amino acid level and false neurotransmitter (FNT) level during ultra-endurance exercise. Twenty-one male Japanese participants of the 1993 Ironman Japan Contest, held at Lake Biwa, were examined. Blood sampling and a questionnaire on the Profile of Mood States (POMS) test were collected two days before, immediately after and one-day following the race. The POMS questionnaire showed various changes especially due to fatigue. Indeed, the fatigue score significantly increased after the race. Although the confusion score significantly increased after the race, it quickly recovered to the pre race level the following day. The plasma concentration of the branched-chain amino acids (BCAA) decreased after the race, while the level of aromatic amino acids (AAA) increased, thus resulting in a significant decrease in the BCAA/AAA ratio. The plasma level of octopamine, one type of FNT, significantly increased after the race (p<0.01) . The blood ammonia level increased after the race, but recovered to the pre-race level one-day after the race. Although no change was observed in the total tryptophan (Trp) level, the level of free Trp significantly increased during the race. The significant increases in the plasma 5-hydroxyindoleacetic acid (5HIAA), homovanillic acid (HVA) and HVA/dihydroxyphenylacetic acid (DOPAC) ratios thus suggest the serotonin (5 HT) and dopamine (DA) neuron systems activated after the race. In conclusion, ultra-endurance exercise caused a disorder of both the amino acid and monoamine metabolisms. Furthermore these changes were also related with mood changes, especially fatigue, i. e. central fatigue. These results suggest that the measurement of both the plasma BCAA/AAA ratio and FNT may therefore be useful in quantifying exercise induced central fatigue.

Lambl's excrescences are the fibrous structures which are attached to the heart valve, and usually the presence of Lambl's excrescences alone is not an indication of operation. The operative indications of isolated Lambl's excrescence is still controversial, because some reports indicated cross relationship between Lambl's excrescences and cerebral embolism. Based on these facts, we discussed our 3 cases of Lambl's excrescences. Two of the cases had been complicated with severe mitral regurgitation and Lambl's excrescences were resected at the time of mitral valve plasty. In another case, Lambl's excrescence was found with echocardiography during chronic heart failure therapy. This patient had a past history of cerebral infarction, but no relationship of cerebral infarction was suggested. In this case, cardiac surgery was not required, so we followed isolated Lambl's excrescence without resection in this case. One operated case, which had infective endocarditis was suspected by echocardiography, had slighted inflammatory reaction but blood culture was negative. Diagnosis of Lambl's excrescence was made by histopathological examination. One report suggested that the cause of the cerebral infarction is not Lambl's excrescence itself but the thrombi around Lambl's excrescence. However, we hesitate to operate on isolated Lambl's excrescence. Based on some reports, it is useful to resect Lambl's excrescence when a concurrent cardiac operation is carried out to avoid cerebral embolic events.

This paper focuses on new technologies that are practically useful for telemedicine. Three representative systems are introduced: a Digital Video Transport System (DVTS), an H.323 compatible videoconferencing system, and Vidyo. Based on some of our experiences, we highlight the advantages and disadvantages of each technology, and point out technologies that are especially targeted at doctors and technicians, so that those interested in using similar technologies can make appropriate choices and achieve their own goals depending on their specific conditions.

Purpose: We examined the safety and efficacy of cataract surgery and postoperative management in our hospital and at the homes of the patients who live on medically underserved remote.
Patients and methods: A total of 27 patients (54 eyes), who were followed in our hospital or at their homes were enrolled in this study. Cataract surgery was performed on them between January 2009 and January 2010 and we could follow up six months postoperatively. We divided these patients into two groups:group I (GI) consisted of 13 patients who could come to our hospital regularly during both preoperative and postoperative periods, and group II (GII) consisted of 14 patients who could not come to our hospital regularly during either preoperative or postoperative periods. Cataract surgeries were performed on all the patients in GI and GII in our hospital. The patients in GI were hospitalized for three days and those in GII were for seven days. After cataract surgery, the patients in GI had their eyes checked regularly in our hospital and those in GII were in their homes where the doctor visited. Postoperative ophthalmic clinical tests were conducted to examine visual acuity, intraocular pressure and fundus.
Results: GI comprised three males and 10 females. Their age averaged 79.3. GII comprised four males and 10 females. Their age averaged 82.6. Preoperative ophthalmic examinations found that preoperative average visual acuity (LogMAR and decimal visual acuity in parentheses) and spherical equivalent in GI and GII were 0.69 (0.41), 0.80 (0.33) and -0.43 dioptors, -0.42 dioptors respectively, showing no significant differences between the two groups. Postoperative ophthalmic examinations found that, best corrected visual acuity (LogMAR) was significantly increased to 0.36 (0.66) and 0.44 (0.53) in GI and GII respectively, showing no significant differences either.
Conclusions: We concluded that we could get safe and efficient cataract surgery and postoperative management combined with prolonged hospitalization and house calls on the patients who live in the isolated islands.

The lifetime incidence of cancer in women is about 50%, with some gynecological cancers increasing, and the prevalence of depression in patients is assumed to be about 12-25%1）. Depression is thought to affect not only suicide but also death from cancer2）, and it is important to provide psychological care to patients as survivors from the time they are diagnosed with cancer. Psychotropic drugs are often chosen for treatment, but side effects such as extrapyramidal symptoms, drowsiness, and constipation are observed, and the quality of life of cancer patients can be increasingly compromised.In this article, we report on seven cases of gynecological cancer survivors who experienced significant efficacy of kososan for the depression and anxiety resulting from stress they felt during various processes such as diagnosis, notification, treatment, recurrence, and best supportive care (BSC). Kososan is a qi-regulating formula, and its efficacy in improving depression has been described since ancient times. In particular, it can be widely used for qi problems of women with a deficiency pattern, and its application to gynecological cancer treatment is considered to be very useful.
