The menstrual cycle and response to erotic literature

133 undergraduate females responded to a pre-experimental questionnaire assessing their contraceptive use (28% on contraceptive pills), sexual experience (71% had had sexual intercourse), and present phase of menstrual cycle. Ss then read an erotic story intended to induce sexual arousal. Results of a self-report postexperimental questionnaire assessing sexual arousal and genital stimulation show no significant response differences based on menstrual cycle phases for Ss not using contraceptive pills. Greatest degree of arousal and sensation was experienced by Ss on contraceptive pills who were in the menstrual phase of the cycle; least arousal and sensation was experienced by Ss on contraceptive pills who were in the premenstrual phase of the cycle.

Ultrastructure of the spermatozoa and spermiogenesis in New Zealand freshwater eels (Anguillidae)

The spermiogenesis and sperm ultrastructure of Anguilla australis schmidtii and A. dieffenbachii is described. During spermiogenesis the chromatin material condenses into the crescent-shaped head of the mature sperm. By elongation of the sperm head the mitochondrion is displaced to the anterior of the head remote from the posterior centriolar apparatus. A ciliary rootlet becomes segregated during spermiogenesis to form a membrane covered, striated, rod-like appendage. From the proximal centriole arise two sets of filaments, each containing three subfibrils. One group of five filaments extends anteriorly along the inner concave side of the head. A group of four modified filaments pass along the outer, convex, side. The middle subfibril B of each triplet in the group of four filaments is flattened and joins the two subfibrils A and B, forming a binocular shaped structure. The motile flagellum has a 9+0 axonemal pattern.     

Acute poststreptococcal glomerulonephritis mimicking Henoch-Sch?nlein purpura

Two children with acute glomerulonephritis, cutaneous vasculitis, and abdominal pain are reported. One child also had transient arthralgia and gastrointestinal hemorrhage. Although the clinical presentation mimicked many of the features of Henoch-Sch?nlein purpura, both patients had unusual variants of poststreptococcal glomerulonephritis.     

Long term results of treatment of carcinoma of cervix

In this survey of 602 patients treated for carcinoma of the uterine cervix during the period 1944--1968 (with a 100 per cent follow-up) survival rates at 5, 10, 15 and 20 years after radiotherapy were 41, 28, 18 and 11 per cent. The crude five-year cure rate of over 70 per cent for Stage I and 58 per cent for Stage II cases and an overall five-year survival rate of 42 per cent for all stages compares favourably with results published from other institutions in the United Kingdom.     

Selective analysis for adenosine using reversed-phase high-pressure liquid chromatography

A high-pressure liquid chromatographic procedure for the selective determination of adenosine in the presence of other nucleic acid components is reported. Reversed-phase microparticle columns and an isocratic elution mode of dilute potassium dihydrophosphate and anhydrous methanol were used. The analysis is specific for adenosine and is achieved in less than 10 min. An example of the use of this analysis in a biomedical study is reported.
