A 51 years old farmer was in unconscious state when he was brought into our hospital. Four days before admission he handled “Nissol” and low toxic organophshor “Smithion” about 9 hours at his farm of apples.
Three days before he noted nausea, vomiting, headache, dizzines, sweatiness and light fever. In the midnight convulsion of limbs occured. Two days before symptoms became progressively worse.
Examinations on admission revealed depression of blood pressure (100-70), incipient rise of body temperature, low blood sugar level (45 mg/dl), concussion of eye-ball and Babinski's sign.
Then as an intoxication of Nissol we treated the patient with glucose solution (5 or 50%), acetamide, antibiotics, phenobalbital, cardiac stimulants and atropin. Fourteen hours after admission he recovered consciousness.
Low blood sugar level and depression of blood pressure continued while about 7 days.
He was out of hospital on the 20 th day.

A 30-year-old woman who had no specific symptom was diagnosed with Turner syndrome at the age of 6 years. Subsequently, she was followed up at a hospital. However, she stopped going to the hospital when she was 18 years old. At 30 years of age, she underwent examinations involving echocardiography and enhanced chest CT at a hospital, which revealed severe aortic valve regurgitation and extreme dilatation of the aortic root. We performed the Bentall procedure through a median sternotomy following which she had an uncomplicated postoperative course. Aortic root enlargement increases the risk of aortic dissection in patients with Turner syndrome. However, no aortic events occurred before the surgery in this case. We considered the reason was related to the mosaic karyotype of this case.

Ultrasonic vocalizations (USVs) are essential communicative sounds used between rodent pups and their mother. Rat pups emit USVs in stressful situations, such as when they are cold or separated from the nest. We verified the ontogenetic changes in USVs emitted by infant rats isolated from their mother during the pre-weaning period. The number of calls, and the median frequency and first peak of frequency of the calls were measured at 1, 3, 5, 7, 10, 12, and 14 days postnatal age in Wistar-Imamichi rats. Pups were placed in a cold glass beaker and USVs were recorded for 5 min. The number of calls increased to a peak on day 5 and then gradually decreased. The median frequency of calls decreased slowly during the first 12 days, and then increased slightly on day 14. Similarly, the first peak frequency of calls was the highest on day 1, and then decreased gradually by day 12. A small increase was observed on day 14. These changes in frequency were correlated with the physical development of the pups, whose body weights increased significantly with age except during postnatal days 7-10.
