PURPOSE: To evaluate normal variations and thus to avoid confusion in differentiation from lesions of the accessory structures (rhomboid fossa, foramen for supraclavicular nerve, conold tubercle) of the clavicle in chest radiographs. MATERIALS AND METHODS: We studied the variations of the clavicle in 300 chest radiographs (134 men, 166 women) and 355 dry bones (right 166, left 189; 151 men, 74 women, 130 unknown sex). RESULTS: In chest radiographs, the incidence of the depressed rhomboid fossa was 229 cases (39.5%;male 52.0%, female 29.9%);the flat type was 329 cases (56.9%;male 45.7%, female 65.7%);and the elevated type was 20 cases (3.5%; male 2.4%, female 4.3%). In the dry bones, the incidence of the depressed thombold fossa was 129 cases (57.3%;male 59.6%, female 52.7%);the flat type was 65 cases (28.9%;male 24.5%, female 37. 8%) ;and the elevated type was 31 cases (13.8%;male 15.9%, female 9.5%). The incidence of the foramen for supraclavicular nerve was 0.8% in chest radiographs, and 1.4% in the dry bones. The incidence of the elevated conold tubercle was 65.1% (male 64.0%, female 65.9%) in chest radiographs, and 96.9% (male 95.4%, female 100.0%) in the dry bones. CONCLUSIONS: The incidence of the depressed rhomboid fossa in chest radiographs was higher in men and the right clavicle. The incidence of flat rhombo~d fossa in chest radiographs decreased according to increase of age. The foramen for supraclavicular nerve was occasionally found (0.8% in chest radiographs; 1.4% in the dry bones).

We investigated the occurrence of color vision loss in 70 organic solvent mixtures exposed workers and in 47 controls. Color Vision was assessed with a color arrangement test designed to identify the defective color sense, the Han Double 15-Hue Test. The results of the test were no significant difference between exposed workers and controls in the proportion of subjects who committed one or two errors. Quantitative analysis, using color confusion index(CCI), showed no signifiant difference between exposed workers and controls. A significant linear correlation was present between age and CCI in both exposed workers(CCi=0.0056age + 0.94; r=0.23; p<0.05) and controls(CCI=0.0066age + 0.86; r=0.33; p<0.05). Qualitative analysis of the patterns on the hue circle showed that the prevalence of acquired dyschromatopsia was 21% in both and no significant difference. Multiple regression analyses showed that age was significantly related to color vision loss. These results did not provide evidence of a relationship between organic solvents exposure and incidence of color vision loss. In field studies for monitor the people at risk of the acquired color vision loss involving low-dose organic solvents exposed workers, both quantitative and qualitative information should be considered.

Hereditary angioedema is a rare genetic disease transmitted with a autosomal dominant trait result of a quantitative or functional defect of Cl inhibitor. We report three cases of heriditary angioedema from the same famly respectively the 35-year-old sister, the younger bn)ther of 32, and the younger sister of 20 The older sister died due to her airway being obstructel by acute laryngeal edema, and her you igirbrother and sister experienced recurrent episodes oswelling on the hand and forearm. The ore we examined the two patients serum complement levils to confirm diagnosis. In both, the r;ults showed decreased levels of Cl inhibitor and C4 which are the evidence of hereditary a giedema. The younger sister has been administered danazol (600mg/day) to prevent angioedem or 8 weeks, and we have not yet found a recurrenc of he symptoms. However, well cont ol the dosage of danazol because amenorchea has developec.

Phosphoinositide-specific phospholipase C(PLC) is known as a key enzyme which produces two major second messengers: diacylglycerol and inositol 1,4,5 trisphosphate. Although it has been suggested that PLC beta isozymes have important roles in nervous system, less is known about the function of PLC beta in development of nervous system. We have localized the mRNA expressions of PLC beta isozymes in the postnatal rat brains by id firm hybridization histochemistry. In the postnatal rat brains, each isozyme of PLC beta showed differential expression pattern. The expression of PLC beta1 mRNA was found in various areas including olfactory bulb, cerebral cortex, caudate putamen, hippocampus, dentate gyrus, and cerebellum. In general, the expression in these areas was gradually increased after birth (PO) until postnatal day 21 (P2l) and slightly decreased to adult level. The expression of PLC beta2 mRNA was not found in postnatal rat brains. The expression of PLC beta3 mRNA was found from P0, peaked at Pl4, and decreased to adult level in the purkinje cells of cerebellum. PLC beta4 mRNA was strongly expressed in the thalamus, cerebellum, cerebral cortex, and olfactory bulb. In these areas, the expression was gradually increased after birth, peaked at P2l, and decreased to adult level. In whole body parasagittal sections of 18 day old rat embryo, PLC betal mRNA was exclusively expressed in nervous tissue, PLC beta3 and PLC beta4 were expressed in various tissues, and the expression of PLC beta2 was not found in any kind of rat tissues. From the different spatiotemporal mRNA expression patterns of PLC beta isozymes in the postnatal rat brains, it is suspected that each PLC beta isozyme may have specific role in signal transduction for postnatal development of rat brain.

Polymorphic reticulosis(PMR) is a unique clinicopathological entity of unknown etiology, which commonly present as an aggressive, necrotizing lesion of the upper respiratory tract. It is a separate nosologic entity from Wegener's granulomatosis and idiopathic mildine destructive disease. The origin of the cells composing polymorphic reticulosis has been controversial. We reviewed 15 cases of polymorphic reticulosis with respect to clinical and histologic bases, and immunohistochemical studies were done using UCHLI (CD45RO), as a T cell marker, CD-20 as a B cell marker and alpha- I -antichymotrypsin as a histiocytic marker. Almost all cases showed characteristic histologic and immunohistochemical features similar to those of peripheral T cell lymphoma. Thus, this study indidcated that polymorphic reticulosis is a type of malignant lymphoma of T cell lineage.

Met protein is a transmembrane 190 kD heterodimer with tyrosine kinase activity, encoded by c-Met oncogene. It serves as a high affinity receptor for hepatocyte growth factor (HGF)/scatter factor (SF), a cytokine which stimulates cell proliferation, motility, and invasion. In this study, we immunohistochemically evaluated the expression of Met/hepatocyte growth factor receptor in colorectal cancers. Met protein was expressed in 31 of 72 patients (43.1%). The staining pattern was cytoplasmic in nature, present throughout the tumor, and showed variable intensity from case to case. The relationship between the expression rate and intensity, and age and sex of patients, tumor size (p=0.645), tumor site (p=0.902) and tumor differentiation (p=0.844) was not statistically significant. The expression rate and intensity were significantly correlated with lymphovascular invasion (p=0.001), lymph node metastasis (p=0.010), depth of invasion (0.019), and stage (p=0.023). Cytoplasmic accumulation of Met protein was not associated with enhanced PCNA index of tumor cells (p=0.052). These results suggest that Met protein may play an important role in the invasion and metastasis of colorectal cancer cells.
