Measurement of the normal pituitary gland height was performed on magnetic resonance (MR) images of 144 subjects with no known or suspected pituitary or hypothalamic diseases. Midsagittal T1 weighted images (T1WI) were used for measurement, and mean vertical height according to age and sex group was obtained. In all age groups, the pituitary height was greater in females than in meles, The group of 0-9 years in both genders showed the minimum mean pituitary height, The maximum mean height was observed in the 10-19 years age group in both genders. The height gradually decreased with increasing age after age 20 years. There was no subject with a height more than 9.0 mm in females or 8.0 mm in males. In conclusion the measurement of the normal pituitary pland height using mid sagittal MR imaging can be used for the evaluation of the pituitary gland lesions.

BACKGROUND: Cardiac hypertrophy is the compensatory response of the myocadium to increased workload. Compensatory mechanisms come into play when the hypertrophied heart can no longer accommodate the increased demand or persistent stimuli. Although it has been reported that the molecular changes in hypertrophied hearts that initially mediate enhanced function may contribute to the development of heart failure, the structural/biochemical/molecular basis for myocardial contractile failure is still obscure. This study was aimed to clarify the structural basis for relation between hypertrophy and failure. METHOD: Nine pairs of rabbits were sacrificed at 8,12,24,48 hours and 1,2,4,6,8 weeks after experiment aortic constriction. There hearts were studied with routine histopathology. Each heart was weighed and compared with total body weight. Multiple sections were embedded in paraffin, sectioned at 5um, and stained with hematoxylin and cosin and Masson's trichrome and analysed. RESULTS: The heart weight to body weight ratio(g/Kg) increased progressively with time after aortic banding. Banding of the aorta in the rabbit resulted in multifocal areas of myofiber degeneration, necrosis and fibrosis through the wall of the left ventricle, in the papillary muscles of the left ventricle and in the left ventricular portions of the interventricular septum in rabbit of 6 and 8 weeks after aortic banding. By 4 weeks after banding, the foci of necrosis were not observed. CONCLUSION: There findings suggest that the increased necrosis, fibrosis in animals with cardiac hypertrophy induced by banding the aorta may play a role in progression to heart failure.

The serodiagnostic test of syphilis employed with the greatest freguency in this country is the VDRL procedure which is one of the flocculation test utilizing cardiolipin-lecithin as an antigen. As well known, the immunologically nonspecific nature of this test relegates it only to screening test, so that all the sera displaying weakly reactive or reactive VDRL in the absence of definite evidence of present or past syphilis should be confirmed by using the specific treponemal antigen tests. However, there are only lirnited numbers of institutions at which the specific treponemal antigen tests are carried out, because the tests usually need quite coaiplicatnl technology and specifically trained personnel. The Treponema. pallidum hema.gglutination assay (TPHA) which was first described by Rathlev in 1965 and established as more improved and standardized procedure in serodia,gnosis of syphilis by Tornizaxva and Kasamatsu (1966) has been found to h as sensitive and specific as the technically more complicated Fluorescent treponemaI antibody absorption (FTA-ABS) or Treponema pallidum immobilization (TPI) po cedure by rnany investigators from different parts of the world during these 10 years. The TPHA has also been found to have definite advantage over the other tests because it is easy to perform and economic. The present authors felt. that the TPHA meight be the most reasonable method to be used in this country and decided to evaluate it in the serodiagnosis of problem cases. Sera from 516 presumed normal persons, 686 pregnant women ancl 1345 patients with various diseases other than syphilis were screened with the standard VDRL procedure as described and recommanded by USPHS. Out of these, 475 of t.he presumed normal persons, 646 of the pregnant women and 1243 of the patient group wit;h various diseases other than syphilis v;ere serologically nonreactive and 10, 12 and Rl sera from each of the above groups, respectively, were found to be true syphilitc with definite evidence of clinical signs or history of syphilis. Thirty-one out of the presumed normal persons, 28 out of the pregnant women and 71 out of the patient group with various diseases other than syphilis showed either weakly reactive or reactive VDRI, in undiluted sera without definite evidence of syphilis and these 130 sera from 130 persons were the subject of the present study. The TPHA was carried out on these 130 sera. according to the ma.nual MEA-TP instructed by National Institute of Health, Japan. The reagents used in this study rvere rnanufactured and supplied hy the Fujizoki Pharmaceutical Co. Ten (32.3%) out of the R1 sera from preaumed normal persons, 11 (39.4%) out of the 28 sera from pregna.nt women a.nd 28 (69.4%) out of the patient group with various disea ses other then syphilis showed reactive TPHA. Eighty-seven of the total 130 sera showed weakly reactive VDRL so called rough result and 19 (21.8%) Of these 87 sera showed reactive TPHA, while 30(69.8%) of the 43 sera which showed reactive VDRL were found to be TPHA reactive. These results arc in general agreement with those of other investigators confirmed by the more complicated FTA-ABS or TPI. The overall incidence of syphilis was 3.87%, 3.35% and 4.38% in presumed normal persons, in pregnant women and in patient group with various diseases other than syphilis respectively. Considering the relative lack of study concerning to the false positive reactions in this country, these results may be helpful to the clinician to rnake a cert.ain diagnostic decision when they meet such a patient whose VDRL is weakly reactive or reactive in the absence of definite evidence of syphilis. The authors concluded that: the MHA-TP technique is easy in performance, economic and highly specific in serodiagnosis and that this technique is highly recommanded in this country. * The authors thank Fujizoki Pharrnaceutical Company, Tokyo, Japan which provided the TPHA reagents used in this study.
