Several UV-sensitive (
rad) mutants were tested for their responses to photolytic binding of an azide analog of ethidium. All mutants were more sensitive to killing by the photolytic treatment with this drug than normal strain but this sensitivity was dependent on the growth phase of each mutant. In late exponential phase, two mutants were classified as supersensitive (
rad l, 3), while two (
rad 6, 52) were more like the normal strain. Respiration-deficient (petite) mutation induction of late exponential cells was quite different from the cell killing effect. Almost all surviving cells of
rad 1, 9 and normal strain were converted to petite mutants by photolytic treatment with 5-l0 μM of ethidium azide. In contrast,
rad 3,
rad 6 and
rad 52 mutants were rather resistant. Early exponential cells of
rad 6 and
rad 52 were supersensitive to the killing effect while petite induction was the same as in normal strain.

Hyperdolichocrany in the medieval adult males of Midwestern Kyushu (near Kumamoto city), particularly concerning the secular changes of the skull forms, are presented and discussed. While the mean cranial index of the modern Midwestern Kyushuites was mesocranic, the mean cranial index of the medieval Midwestern Kyushuites was hyperdolichocranic of 68.1. Concerning the medieval Kamakura Japanese, Suzuki showed their skull forms to be dolichocrany in the mean cranial index of 74.2. The cranial indexes in the Midwestern Kyushuites have increased from the medieval period to the present-pay.

Phospholipase A
2 caused the release of catecholamine from isolated bovine adrenal chromaffin granules. The effect of phospholipase A
2 was dependent on the existence of calcium in the medium. The concentration of calcium required in this process was in the order of 10
-4M. In the coexistence of phospholipase A
2 and catecholamine release factor (CA-RF), even a low concentration of calcium (around 10
-6M)was sufficient to evoke a prominent release of catecholamines. Calcium is the central ion in the secretion of catecholamines and the influx of calcium is the critical step to trigger the secretory process. Such an effective concentration of calcium (10
-6M) observed in a cell free system is sufficiently derived from the influxed calcium upon stimulation of adrenal medulla by acetylcholine, the physiological secretagogue of catecholamine.

Vibration transmissions in the bones through the wrist joints of chain-saw operators were studied by a high-speed cineradiographic method. The results obtained were : 1) The amplitudes of the bone vibrations were clearly attenuated through the wrist joint, 2) The bones showed greater amplitudes than the forehandle, 3) The base of the ulnarstyloid process showed the greatest amplitudes in the distal forearm and 4) Frequencies of the bones might be within the resonant frequency of the hand. It was concluded that the high-speed cineradiographic method was the only useful technique to date for measuring bone vibrations. However, it is complicated and expensive.

The value of
67Ga scintigraphy particularly for detection of extrathoracic involvement by sarcoidosis was evaluated on 26 cases and the following results were obtained: 1) The positive rate of
67Ga scintigraphy in the orbital region was lower than that of clinical examination but in positive cases
67Ga accumulated symmetrically in the lacrimal gland region and this pattern is highly suggestive of the diagnosis. 2) In the salivary gland, nose and pharynx,
67Ga scintigraphy detected more abnormalities than clinical examination and contributed to the recognition of the extent of the disease. 3) In the abdomen and pelvis, there were few positive cases through
67Ga scintigraphy as well as through clinical examination. Thus
67Ga scintigraphy can be useful for detection of involvement by sarcoidosis in the head and neck regions.

The linear pitch model is examined by comparing its prediction with experimental data quantitatively. The pitch model comprising two linear transformation systems ; the peripheral spectral analyzer and the central pitch processor, cannot predict pitch shift of inharmonic complex tones accurately. If the model has non-linearity in its peripheral system, it can predict the pitch shift phenomenon fairly well. As long as the central pitch processor is linear, the multimodal histogram of pitch matching cannot be explained. On the other hand, the pitch pattern predicted by the pitch model using the non-linear central processor is similar to the pattern of the pich matching histogram. So, it is supposed that the pitch model consisting of non-linear transformation in the central system, as well as in the peripheral part, can account for the pitch phenomena quantitatively.

Although ectopic pregnancy is a rare condition, it causes significant mortality if it ruptures. In the case described in this paper, unruptured tubal pregnancy with the living fetus at the ampular part was echographically diagnosed by the real-time electronic linear scanning method. Its echographic characteristics are presented with the review of the literatures. It was concluded the diagnosis prior to rupture will reduce mortality.

Two cases of acute subdural hematoma developed without severe head injury were reported. There was no cerebral contusion or laceration, and the only bleeding sources were pinholes in the walls of surface cortical arteries near the Sylvian fissure. Reports on acute subdural hematomas of arterial origin are reviewed and mechanism of the development of bleeding is discussed.

A surgical repair of recurrent umbilical hernia in a case of a 4-year-old boy with Ehlers-Danlos syndrome is described. In a previous operation, he had postoperative wound bleeding for a week and had recurrence of the hernia. Hemostatic studies revealed normal results. The patient was treated successfully using multiple silk and dexon sutures, tantalum wire sutures and microfibrillar collagen hemostat during the operation.

The present report identified the digested remains in the corpse's stomach using the scanning electron microscope. The specimens were obtained from an about 20 years old female eat 2 month postmortem time. The digested remains were 0.8×2.0 cm in size and were a dirty reddish-purple color. As these specimens in the stomach were very similar in macroscopic features to the pericarp of kidney beans, we also observed the pericarps of uncooked, fried and boiled kidney beans using the scanning electron microscope for the control specimens. The ultrastructures of the digested remains were observed as remarkable deformations caused by cooking, digestion and putrefaction. However, the spiral vessels and stomata, quite similar in ultrastructures to those of the control specimens, were recognized. On these grounds, we identified the examined specimens as digested remains of the pericarps of kidney beans.

There are few people who can definitely and openly deny the glorious history of Jesus Christ, although some emotional people often speak out against it. Scientific approaches and interpretations of Jesus Christ's life are made by such people, but it happens that they unexpectedly manifest their involuntary perplexity and their upside down affection for Jesus Christ. It is very likely that the image of Jesus Christ varies in the eyes of contemporary people who are living in a dangerous time when by a push of a button their world can be converted into a blazing Hell. They are unable to believe in God as straightforwardly as their ancestors did, but are still obsessed by the image of God, by their
own image of Jesus Christ. This is a hesitating, personal investigation of how they manifest their own faith in life and affection for the Savior.
