A unilateral variation in the origin and distribution of the arterial pattern of the human upper extremity on the right side is reported on. Apart from its usual branches, the third part of the right axillary artery gave origin to a common branch, the profunda brachii artery and the superior ulnar collateral artery. The right brachial artery, at a point 5.0 cm distal to its origin, bifurcated into the radial and ulnar arteries; their origin was in a position opposite the usual location. The radial artery continued on the medial side of the arm for 2.5 cm and crossed the ulnar artery anteriorly to gain a lateral position in the arm. The inferior ulnar collateral artery arose not from the brachial artery, but from the ulnar artery. A muscle variation was also observed in the right hand, which is compatible with the notion variations within one system of a limb will frequently be accompanied by variations in other systems of the same limb.

Long and short axis scans were performed and findings of each were separately classified according to a five-grade system, and the results were correlated with the actual extent of tear observed during surgery. Internal echogenicity and subacromial impingement were analyzed before and after surgery. A accuracy of US in detecting rotator cuff tears was analyzed. In addition, the correlation between cuff shape observed by US before surgery and actual shape observed during surgery was assessed. It was noted that cuff thinning and abnormalities in shape did not recover to normal after surgery. However, in the cases of discontinuities observed by US before surgery, US findings indicated that the torn cuff was anchored to the greater tuberosity and functional during active motion. Although post-operative US findings were not normal, clinical results were good in most cases. Sensitivity of US for detecting rotator cuff tear was 100% and specificity 94%. US is non-invasive, cost effective and allows the physician to examine the joint while it is in motion. Therefore, at this time, we use US as a screening method for detecting rotator cuff tears. Furthermore, US allows us to check for re-tears while the joint is in motion, which is essential for accurate diagnosis.

Patients studied were divided into three groups according to the type of factor responsible for their delirium. We termed these causal factors precipitating, facilitating and predisposing factors. Twenty-one patients exhibited precipitating factors, the most common of which were overmedication and poisoning. Almost all these cases were treated with psychotropic drugs. Facilitating factors were judged responsible in nine cases. In six of these, admission to a hospital was thought to be the facilitating factor. Thirteen patients who had only predisposing factors were treated with psychotropic drugs while 27% of patients without precipitating factors were successfully treated for delirium without the use of such drugs.

Using this panel, we evaluated 26 anti-cancer agents: three alkylators, three platinum compounds, four antimetabolites, one topoisomerase I inhibitor, five topoisomerase II inhibitors, seven antimitotic agents and three tyrosine kinase inhibitors. This panel showed the following: a) Drug sensitivity patterns reflected their clinically-established patterns of action. For example, doxorubicin and etoposide were shown to be active against small cell lung cancer cell lines and mitomycin-C and 5-fluorouracil were active against non-small cell lung cancer cell lines, in agreement with clinical data. b) Correlation analysis of the mean graphs derived from the logarithm of IC50 values of the drugs gave insight into the mechanism of each drug's action. Thus, two drug combinations with reverse or no correlation, such as the combination of cisplatin and vinorelbine, might be good candidates for the ideal two drug combination in the treatment of lung cancer, as is being confirmed in clinical trials. c) Using cluster analysis of the cell lines in the panel with their drug sensitivity patterns, we could classify the cell lines into four groups depending on the drug sensitivity similarity. This classification will be useful to elucidate the cellular mechanism of action and drug resistance. Thus, our drug sensitivity panel will be helpful to explore new drugs or to develop a new combination of anti-cancer agents for the treatment of lung cancer.

MTT-95 cells differentiate into mature basophilic cells in culture medium with no chemical component or cytokine. Surface phenotypes were as follows: CD11b 79.3%, CD13 92.4%, CD33 99.8%, CD34 87.9%, CD41a 77.6% and HLA-DR 0.3%. MTT-95 cells were strongly positive for glycoprotein IIb/IIIa by immunohistochemical staining and revealed metachromatic granules. MTT-95 cells seem to possess characteristics of both megakaryocytes and basophils. These findings suggest that MTT-95 cells are basophil progenitors. MTT-95 cells might be useful in the study not only of the biological aspects of basophils, but also of the diversities of AML (M7).
