Abstract
The Tasmanian Cancer Registry carried out population-based surveillance of non-melanoma skin cancer (NMSC) from 1978 to 1987. A total of 8,651 NMSC were recorded in 7,160 individuals, representing an age-standardized rate of 161/100,000 per year. Ninety-four percent of cases were based on histological diagnosis. Incidence of basal-cell carcinoma (BCC) was higher than the incidence of squamous-cell carcinoma (SCC). The incidence of NMSC was twice as high in men as in women. Incidence increased substantially with age, more markedly for SCC than BCC. For most body sites, BCC was more frequent, but on highly exposed sites such as the backs of hands, lower limbs in women and ears in men, the incidence of SCC was higher. There was an overall increase of 7% per year in the age-standardized incidence rate of NMSC. The increase was more marked for BCC than for SCC, and was consistent across age groups and both sexes. A first NMSC during the study period was associated with a 12-fold increase among men and a 15-fold increase among women in the risk of development of a new NMSC within 5 years, when compared with the NMSC incidence recorded for the population as a whole.

Abstract
140 patients with brain tumor were treated by CT-guided stereotactic injections of radionuclides, such as Aurum-198 (198 Au), Phosphorus-32 (32 P) and Yttrium-90 (90Y). Of these patients aged from 3 to 67 years (average 37), 64 were male and 76 female. Astrocytoma was found in 75 patients, craniopharyngioma in 46, metastatic carcinoma in 7, meningioma in 5, germinoma in 4 and pituitary adenoma in 3. The tumors were located in the deep part or functionally critical area of the brain. After 267 times of injection of colloidal isotopes, no major adverse effects or complications occurred. Follow-up for 6 to 48 months showed improvement in symptoms in 104 (74.3%) patients and CT scanning showed the diminished tumors.

Abstract
We have evaluated the role of circulating serum immunoglobulins (IgG) which inhibit the growth of thyroid in the etiology of thyroid atrophy in endemic cretinism. Twenty nongoitrous cretins (13 women and 7 men, age range: 9-33) were classified on the basis of clinical criteria for cretinism in China. They were born and living in an iodine deficient area, Xinjiang, northwest China. Antimicrosomal antibody titers were negative in all serum. Nine patients (seven women and two men; age range: 11-23) were biologically primary hypothyroid. Seven subjects were of a myxedematous form and two subjects were of a mixed form. We have studied thyroid-growth inhibiting immunoglobulin (TGII) activity that was measured as an inhibitory effect of 4 mg/ml IgG on TSH-induced [3H]-thymidine incorporation into the DNA of a rat thyroid follicular cell line, FRTL5 cells. Six (five women and one man) out of the nine patients with primary hypothyroidism (66.7 percent) had TGII. We also measured other growth-blocking IgG that inhibited [3H]-thymidine incorporation into DNA stimulated by insulin-like growth factor-I (IGF-I), a growth factor working through a cAMP-independent pathway. Five (three women and two men) out of nine patients (55.6 percent) with nongoitrous primary hypothyroidism had IGF-I-blocking IgG. These results indicate that TGII plays an important role in atrophy of the thyroid in spite of increased serum TSH concentrations, and IgG which inhibits thyroid growth stimulated by IGF-I also might play a role in thyroid atrophy in some endemic cretins.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The antitumor activity of a new podophyllotoxin spin-labeled derivative, 4-(4''-(2'',2'',6'',6''-tetramethyl-1''-+piperidinyoxy)amino)-4'- demethylepipodophyllotoxin (GP-7) First synthesized by us, was studied in vitro. It was found that the proliferation of SGC-7901 cells was markedly inhibited by GP-7 depending the concentration and exposure time. At concentration of 0.04-100 mg/L, the inhibition rates were 15.5-92.6% ID50 was 0.42 mg/L. After exposure to GP-7 greater than 0.5 mg/L for 24, 48, 72 and 96 h, the inhibition rates of cells were 25.1, 49.0, 71.4 and 84.9% respectively. The dose-response curve of GP-7 on SGC-7901 cell was similar to that of etoposide (VP-16). The colony formation of SGC-7901 cell was also inhibited by GP-7 in a concentration dependent fashion with ID50 1.63 mg/L. At concentrations of 0.1-0.5 mg/L, the inhibitory effects were stronger than that of VP-16. GP-7 decreased the mitotic index (MI) of SGC-7901 cell and had no effect on microtubule assembly and disassembly in vitro, which suggested that GP-7 did not act on M phase.

Abstract
Genes that govern the formation of deoxysugars or their attachment to erythronolide B and 3 alpha-mycarosyl erythronolide B, intermediates of the biosynthesis of the 14-membered macrolide antibiotic erythromycin, were cloned from Saccharopolyspora erythraea (formerly Streptomyces erythreus). Segments of DNA that complement the eryB25, eryB26, eryB46, eryC1-60, and eryD24 mutations blocking the formation of erythronolide B or 3 alpha-mycarosyl erythronolide B, when cloned in Escherichia coli-Streptomyces shuttle cosmids or plasmid vectors that can transform S. erythraea, were located in a ca. 18-kilobase-pair region upstream of the erythromycin resistance (ermE) gene. The eryC1 gene lies just to the 5' side of ermE, and one (or possibly two) eryB gene is approximately 12 kilobase pairs farther upstream. Another eryB gene may be in the same region, while an additional eryB mutation appears to be located elsewhere. The eryD gene lies between the eryB and eryC1 genes and may regulate their function on the basis of the phenotype of an EryD- mutant.

Abstract
The spin labeled derivatives of podophyllotoxin, 4-[4''-(2'',2'',6'',6''-tetramethyl-l''-piperidinyloxy)amino] -4'-demethylepipodophyllotoxin(GP-7,3) and N-podophyllic acid-N''-[4-(2,2,6,6-tetramethyl-l-piperidinyloxy)] thiosemicarbazide(GP-4,5) were synthesized and tested for their anticancer activity against the mouse solid tumors S180 and HepA in vivo, and the mouse lymphocytic leukemia L1210 and human stomach carcinoma SGC-7901 cells in vitro. At equitoxic concentrations, the anticancer activity of GP-7(3) was found to be similar to that of the clinically used VP-16(2). The toxicity of GP-7(3) (LD50231.2 mg/Kg) is 3.3 times lower than that of VP-16 (LD50 69.5 mg/Kg). GP-7(3) exhibits low subchronic toxicity. The total chemical yield of GP-7 (26%) is 4 times higher than that of VP-16 (6%) (based on podophyllotoxin). Therefore, GP-7(3) seems to be a promising new entry into the podophyllotoxin class of anticancer drugs.

Abstract
Lactose absorption capacity was examined in 641 apparently healthy adolescents and adults (447 males and 194 females with an average age of 22.9 years and an age range of 16-46 years) using a field version of the lactose tolerance test with breath hydrogen determination. In the total sample, 89 lactose absorbers and 552 lactose malabsorbers were identified. Lactose malabsorption was most frequent in a subgroup of Han (Chinese) from northeastern China (229 of 248 subjects, 92.3%). Among 198 Mongols from Inner Mongolia, there were 174 lactose malabsorbers (87.9%). The frequency of lactose malabsorption was lowest in a group of Kazakhs, traditional herders from the northwestern region of Xinjiang (149 of 195 subjects, 76.4%). Reported symptoms of lactose intolerance were significantly more frequent in lactose malabsorbers. The findings in northern Han are similar to the reported lactose malabsorption frequency in southern (mainly overseas) Chinese, and correspond with the absence of animal milk from traditional Chinese diets. The relatively low prevalence of lactose malabsorption among the Kazakhs suggests that lactose persistence may be frequent in herding pastoralist populations of southwest Asia.
