Much work has been reported on the chemical, physical and morphological properties of urinary Tamm-Horsfall glycoprotein (THG). Although it was once reported that cystic fibrotic (CF) individuals had a defective THG, more recent data indicate that THG and CF-THG are similar if not identical.No studies on the conformational aspects have been reported on this glycoprotein using circular dichroism (CD). We examined the secondary structure of THG and derivatives under various conditions and have correlated these results with quaternary structure using electron microscopy.THG was prepared from normal adult males and CF-THG from a 16-year old CF female by the method of Tamm and Horsfall. CF female by the method of Tamm and Horsfall.

ABSTRACT A hapten-radioimmunoassay for plasma oestradiol is described and information about the reliability of the method is given in detail. Oestradiol-3-hemisuccinate coupled to keyhole limpet haemocyanin is used for immunization of rabbits. The antiserum utilized for the assay is characterized by its titer, affinity and specificity. Following ether extraction and NaOH-light petroleum partition oestradiol is separated from crossreacting oestrogens by TLC. Oxidation of oestradiol on the plate is prevented by mercaptoethanol. To separate free and antibody bound ligand 250 μg dextran-coated charcoal per tube is used in the presence of bovine serum gammaglobulin (1 mg/ml). The between-assay precision based on 15 different determinations of control samples from normal adult male plasma was 9.4% (C. V.). The mean reagent blank value of 31 determinations was equivalent to 0.3 pg oestradiol and the detection limit in terms of the 99% confidence limit for a single blank value, was equivalent to 4.3 pg oestradiol. A procedure for detecting plasma blanks is described. Plasma oestradiol is separated from approximately all concomitant substances originally present in the sample by enzymatic conversion into oestrone and a second TLC. No plasma blanks could be detected with respect to normal adult male plasma. Normal values for adult males based on 51 subjects were characterized by a median of 17.2 pg/ml and the 95 percentiles of 9.5–27.6.

Data kebahasaan sering merekam nilai budaya. Hanya saja, data kebahasaan masih belum mendapat perhatian untuk kepentingan analisis terhadap dinamikasosial masyarakat yang bersumber pada nilai-nilai budaya. Tujuan penelitian ini adalah untuk menganalisis cerita humor bahasa Jawa Ngapak yang mengandung nilai-nilai budaya dan cara budaya dikonstruksi melalui melalui bahasa humor. Objek kajian tulisan ini adalah wacana humor. Oleh karena wacana humor menggunakan media teks dan tuturan, pendekatan yang digunakan adalah linguistik-antropologi. Adapun metode yang digunakan dalam tulisan ini adalah metode penelitian kualitatif yang menghasilkan data deskriptif berupa ucapan, tulisan, atau perilaku yang diamati, dengan menggunakan tehnik simak. Hasil penelitian menunjukkan bahwa budaya sehat, ajaran agama, dan budaya berbagi terhadap sesama ditemukan dalam humor bahasa Jawa Ngapak itu. Budaya-budaya itu dikontruksi melalui bahasa Jawa Ngapak dalam suasana humor menampilkan realitas masyarakat penutur Ngapak. Ini berarti nilai-nilai budaya ditemukan dalam humor, berupa percakapan manusia maupun percakapan tokoh cerita fable, yang dikonstruksi melalui bahasa Jawa Ngapak untuk merefleksikan realitas. Linguistic data that embody cultural values have not been taken into consideration in analyzing social dynamics. The study aimed at investigating Ngapak Javanese humor story which contained cultural values, and how culture was constructed through the language of humor. Therefore, the humonrous discourses became the main object of the research. The method used in this research is a qualitative which produced descriptive data in the form of speech, written, or observed behavior, and supported with listening technique. As humorous discourses used speech and text media, the study utilized a linguistic-anthropology approach. Healthy life culture, religious teachings, and the culture of sharing were found in the Ngapak Javanese humor stories. These cultures were constructed through the language of humor by the Javanese Ngapak community. In addition, the culture constructed through the Ngapak Javanese language in a humorous atmosphere displayed the reality of the Ngapak-speaking community. This can be concluded that cultural values found in humor, in the form of human speech and fable character conversations constructed through the Ngapak Javanese language displayed the reality of social dynamics.

Abstract We study size-at-age and sexual variability of morphometric characteristics of the marsh frog. According to the size of the body, males were divided into three size-age groups (juvenis, subadultus, adultus), females — into four groups (juvenis, subadultus, adultus, adultus-I). We found that the chronological age of frogs (skeletochronology) does not always correspond to their biological age (size and proportions of the body). We noted that the semi-adult males are reliably larger than females by mean values of 26 studied morphometric characters. Males and females of “adultus” group do not differ by linear body size, significant differences were found in body proportions (7 characters). For the females of “adultus-I” group, the mean values of 26 characters are significantly larger than for “adultus” males. The results of our study showed that with the age of the marsh frog, the level of exhibition, directionality and structure of morphometric sex differences changes.
