Abstract
A 14-month-old infant had a classical Wilms' tumor of the left kidney and subsequently developed a tumor showing predominantly mature mesenchymal elements and lack of cellular atypia in the right kidney. His father had classical Wilms' tumor of the left kidney. The various possibilities regarding the precise nature and mechanism of the development of the tumor in the right kidney are discussed. The similarities and the differences between this tumor and congenital mesoblastic nephroma are noted. The possible relation of chemotherapy to mesenchymal differentiation and maturation in Wilms' tumor is considered. The possibility of an unusual, histologically benign, mesenchymal variant in the spectrum of infantile nephroblastic neoplasia is also suggested.

Abstract
Follicular growth and kinetics were studied in detail in the ovaries of the Indian mole rat (Bandicota bengalensis) during various stages of the estrous cycle; days 7, 12, 15, 19, and 21 of pregnancy; and day 2 postpartum. The sizes of follicles, oocytes, nuclei, and nucleoli were measured. In all rats, regression coefficients, a, and intercepts, b, were calculated in oocyte/follicle, oocyte nucleus/follicle and oocyte nucleus/oocyte regressions. The oocyte reached its maximum size when the average follicle diameter was 117 microns in nonpregnant rats and 131 microns in pregnant rats. The oocyte nucleus attained maximum size when the follicle diameter was 110 microns during the estrous cycle and 111 microns during pregnancy and postpartum. Maximum values of the diameter of the largest antral follicle and average diameter of the four largest antral follicles were observed during proestrus (473 and 442 microns, respectively) and on day 21 of pregnancy (611 and 538 microns, respectively). Chi 2 analysis showed that distribution of various types of follicles was not independent of the stage of the estrous cycle and pregnancy. In estrus and metestrus most of the follicles were between stages I and V. However, by diestrus and proestrus, follicles of all size groups developed. The numbers of stage I and II follicles did not differ as pregnancy advanced. More stage V follicles were present on day 12 than on day 7 of pregnancy; however, their numbers decreased by day 15. Afterwards, progressive increase of stage V and (VI + VII) follicles was observed until day 21. This was accompanied by the shift of follicles from stage (III + IV) on days 19 and 21 of pregnancy and even of stage II on day 2 postpartum. Wherever possible, the results have been compared with previous observations in various rodent species.

Abstract
A study has been made of seasonal changes in the body weights of males and females, and of ovarian and uterine weights, in the Indian mole rat, Bandicota bengalensis, between July 1976 and June 1978, from areas surrounding Ludhiana (30�56'N.,75�52'E.). An attempt has been made to correlate them and peaks in reproductive activity with environmental factors such as daylength, temperature, rainfall and availability of food. During both years of study, the percentage of males was 45.2. The body, ovary and uterus were lighter during winter, and then gained weight, with peaks during April and August-September. Males were generally heavier than females. On the whole, 34.7% of females were either pregnant or lactating. The breeding season extended from mid-February to mid-October. Two peaks in breeding activity (April and August-September), with a decline during June, were separated by a period of reproductive inactivity from November to mid-February. The average litter size was 8.88 (range 5-13). Embryos occurred with almost the same frequency in the left and right uterine horns. The pre-implantation mortality was 9.6% and post-implantation mortality 4.8%; thus the total prenatal mortality was 13.7%. The percentage of embryos found resorbing was 4.1. The results have been discussed in the light of the literature on the reproductive biology of rodents in this region.

Abstract
The genotoxic activity of diesel exhaust emissions, particulate matter, and an organic extract of the particulate matter was evaluated in transplacentally exposed Syrian hamster fetal liver cells. The frequency of sister chromatid exchange (SCE) was determined on day 13 of gestation. The extract of diesel particulate matter caused a dose-dependent increase in the frequency of SCE with a doubling in the incidence above 320mg/kg. The diesel particulate matter and diesel exhaust emissions did not alter the frequency of SCE. The extract and particulate matter did cause a dose-dependent decrease in the mitotic activity of the fetal liver. The in utero SCE analysis was demonstrated to be a sensitive assay for determination of the genotoxic activity of a complex mixture in transplacentally exposed fetuses.

Abstract
The immunoregulatory activity of bone marrow leukemic blasts from five patients with null-cell acute lymphoblastic leukemia (ALL) and two children with T-cell ALL was evaluated. Blasts were studied in co-culture for their effects on the proliferative responses of normal allogeneic peripheral blood lymphocytes to phytohemagglutinin. Mitomycin C-treated null cell ALL blasts from two of five children suppressed the proliferative responses of normal responder cells by 80% and 58% whereas those from two other children enhanced the responses by 118% and 31%. T-cell leukemic blasts from one patient with T-cell ALL exhibited helper cell activity (26%) and T-leukemic blasts from the other demonstrated suppressor cell activity (53%). The helper cell activity of leukemic blasts was associated with stimulating capacity of null blasts in one-way mixed lymphocyte reactions. In six of seven cases, incubation of blast cells with concanavalin A (20 microgram/ml) for 48 hours prior to co-culture with responder cells did not result in the generation of significant suppressor cell activity. Our study suggests that leukemic blasts from certain patients with 'null' and T-cell ALL may possess spontaneous helper or suppressor cell immunoregulatory activity. This functional heterogeneity of leukemic blasts may help in subclassifying the ALL.

Abstract
Innate incapacity to elaborate a protective cellular immunity has been thought to underlie the evaluation of the disease process of lepromatous leprosy. Although both family and twin studies were suggestive of the involvement of some genetic factors, they have so far not been evaluated fully. Keeping this in view, the present study, conducted at the family level, was designed to evaluate the role of genetic factors in determining the type of leprosy in a patient.

Abstract
Penile involvement was seen in 19.5% of 261 patients, aged 11 to 30 years, with tinea cruris. It was more common in patients under the age of 20 years (p less than 0.05). The increased incidence is probably related to the use of langota, a semiocclusive undergarment that may favor the growth of dermatophytes.

Abstract
Irradiated Syrian hamster fetal cells (feeder layer) and rat-liver homogenate (S9 mix) were used to compare their capacity to metabolize 3 known promutagens/carcinogens; BaP, 3-MC and DMBA. DNA-damaging potential was determined by the induction of SCE in V79 target cells. The S9 mix (1/20th strength) was toxic to the target cells and reduced the mitotic index by half with an exposure time of 2.5 h. The feeder layer was not toxic to the target cells and, therefore, was included for the duration of the Expt. The test chemicals elicited a dose-response with both activating systems. At similar concentrations of the test chemicals, the cells grown on the feeder layer showed a greater number of SCEs as compared to those activated by the S9 mix.

Abstract
Reports of acute nonlymphoblastic leukemia occurring after successful treatment of Hodgkin and non-Hodgkin lymphoma (NHL) are appearing with increasing frequency. Two years after completion of LSA2-L2 therapy for stage III, poorly differentiated lymphocytic lymphoma, a 16-year-old boy developed a preleukemic state characterized by a refractory macrocytic anemia with excess blasts, dyshematopoiesis, abnormal cluster:colony ratio on in vitro bone marrow culture, and acquired deficiencies of erythrocyte pyruvate kinase, triose phosphate isomerase, and adenylate kinase. Four months later acute myeloblastic leukemia was evident. The RNA index determined by flow cytofluorometry was increased. Four marker chromosomes were found and involved complex translocation of chromosomes 11 and 17 (t11;l17) in 100% of the cells, and chromosomes 4 (t4q;4) in 10% of the cells. A thorough literature search uncovered four other reports of acute nonlymphoblastic leukemia occurring in children treated for NHL and a total of 58 cases in the adult and pediatric age groups. Over 50% of the patients had AML, were mean over 50 years of age, and were treated with radiotherapy and chemotherapy. It is anticipated that additional cases of second malignancies will be reported in this population of patients whose outlook for the curability of the primary malignancy is 75%.

Abstract
Age of onset of leprosy is merely a subjective information based upon the memory, intelligent appreciation and awareness of the patient and his relatives, in absence of a more reliable method. In the present study, a modification of the conventional method which we named "Complemented recall" method was adopted to determine the age of onset of 400 leprosy patients, in an attempt to collect a better approximate data.
