In vitro uptake of 67Ga-citrate and 59Fe-citrate by DS sarcoma cells in the presence of tumor-bearing animal blood plasma showed a dramatic inhibition of both 67Ga and 59Fe uptakes: about ii/io of 67Ga and 1/5o of the 59Fe are taken up by the cells. Subcellular fractionation appears to indicate no specific binding to cell structures, and the difference of binding seems to be related to the transferrin chelation and transmembrane transport differences

ABSTRACT The anterior, middle, and posterior hypothalamus, the cortex cerebri, the anterior hypophysis as well as the diaphragm of adult ovariectomized rats were incubated in vitro with tritiated 17β-oestradiol. The uptake of tritiated oestradiol was differentially distributed intracerebrally with higher accumulation in the anterior hypothalamus and the hypophysis. Lowering the temperature of the incubation medium caused a reduction in the uptake of radioactivity by the anterior hypothalamus as compared to that found in other brain tissues. Tritiated oestradiol taken up in vitro by the anterior hypothalamus and the hypophysis tended to be retained after further incubation in a steroid-free medium. The addition of non-radioactive 17β-oestradiol to the medium inhibited the uptake of tritiated oestradiol by these tissues. Moreover, pretreatment with non-radioactive 17β-oestradiol in vivo prevented the preferential accumulation of tritiated oestradiol in vitro in the anterior hypothalamus and the hypophysis. These results indicate that oestradiol is preferentially taken up in vitro by the anterior hypothalamus and the hypophysis of the rat.

ABSTRACT The red cell triiodothyronine uptake technique as used in our hospital is described. Incubation time is of almost no importance. The temperature during incubation should be 37° C. Further improvement of the technique is obtained when all blood samples are brought up to 40 % haematocrit prior to incubation. Clinical results are discussed. It is yet too early to give a definite assessment of its clinical value, but it is definitely superior to the measurement of the BMR.

ABSTRAK. Tujuan penelitian ini untuk mengetahui motilitas Ascaridia galli dewasa dalam ekstrak etanol biji Veitchia merrillii. Ekstrak etanol V. merrillii dianalisis fitokimia. Sebanyak 16 ekor cacing A. galli dewasa dibagi kedalam empat kelompok. Cacing pada kelompok pertama adalah kelompok tanpa perlakuan. Cacing pada kelompok kedua diberi 0,6 mg/ml levamisole. Cacing pada masing-masing kelompok ketiga dan keempat diberi 50 dan 100 mg/ml crude ekstrak biji V. merrillii. Motilitas A. galli ditentukan dalam skor persentase setelah 12, 24, 36 jam dengan menggunakan kriteria: 3 (badan bergerak), 2 (hanya sebagian badan bergerak), 1 (tidak bergerak tetapi masih hidup), 0 (mati). Hasil fitokimia V. merrillii mengandung alkaloids, saponins, tannins, flavonoids, terpenoids. Ekstrak biji V. merrillii dosis 100 mg/ml secara in vitro dapat mempersingkat selama 12 jam waktu motilitas cacing A. galli dewasa. Penelitian ini mengindikasikan potensi anthelmintik berbasis herbal untuk pengendalian A. galli.  (Motility of Ascaridia galli adult worms in vitro in ethanolic extracts of Nuts Veitchia merrillii) ABSTRACT. The purpose of this research was to know the motility of Ascaridia galli adult worms in aqueous ethanolic extracts of nuts Veitchia merrillii. The ethanolic extract of the V. merrillii was analyzed. Amount of sixteen head A. galli adult worms were divided into four groups. The first group, worms were left as un-treated normal controls. The second group, worms were treated with concentrations of 0,6 mg/ml levamisole. The third and fourth group, worms were treated with crude aqueous ethanolic extract of 50 and 100 mg/ml concentrations nuts of the V. merrillii, respectively. Motility of A. galli were determined after 12, 24, 36 hour by mean of persentage scored using the following criteria: 3 (moving whole body), 2 (moving only parts of the body), 1 (immobile but alive), and 0 (died). The result of phytochemical V. merrillii contains alkaloids, saponins, flavonoids, tannins, and terpenoids. V. merrillii nuts extract concentrations of 100 mg/ml in vitro can shorten the time motility A. galli adult worms for 12 hours. The study indicated the potential for developing herbal-based anthelmintics to control A. galli.
