Femoral Torsion

The correction of lower extremity rotational deformities, such as tibial and femoral torsion, requires the application of derotational forces. One method of applying such rotational forces during ambulation is through the use of ground contact rotational orthotic devices. Two devices were tested. One device uses parallel rows of slanted rubber ribs and the other has slanted rubber ribs located in a circular array to produce rotational forces when the device strikes the ground during normal walking. It was found that the parallel rowed rib produced a rotation of 5.5 deg during walking and when rotation was prevented, torsional force produced by the device was approximately 20 in-lb. The circular array of ribs produced a complete rotation of 18 deg. When rotation was prevented, the heel produced 21.5 in-lb of torsion. The possible resisting torsion of a normal adult male was determined to be 11 in-lb at an 80 lb applied weight. Therefore it is concluded that the ground contact rotational devices will either provide rotation to the extent of the applied load or will apply torsional force greater than that encountered by normal leg structure.

SummaryWhen 125I-labeled canine prothrombin was given to normal adult dogs intravenously, it was calculated that 240% of the plasma prothrombin crossed the capillary barrier per day, 410% of the interstitial prothrombin returned to the blood stream daily, and 79% of the plasmatic prothrombin was catabolized per day. These data are in close agreement with those observed for bovine prothrombin in calves by Takeda (1970).When derived from normal dog prothrombin, prethrombin-1 is a mixture of 2 polypeptides, one larger than the other, and both present in about equal amounts. The longer peptide, “prethrombin-1-long,” was catabolized twice as fast as prothrombin, and the shorter, “prethrombin-1-short,” 4 times faster. Prothrombin fragment-1 was catabolized by the normal dog still more rapidly.The catabolism of prothrombin was not accelerated in 3 dogs receiving continuous infusions of a thromboplastic emulsion of dog brain. Nor was the level of prothrombin in their plasma remarkably altered.

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.

The presence of Stoloteuthis leucoptera in the Mediterranean is recorded on the basis of three specimens, including an adult male, caught by IKMT and by commercial otter-trawl in the Ligurian Sea. The hypothesis of a recent immigration is discussed.The list of Mediterranean cephalopods (Mangold Wirz, 1963; Torchio, 1968; Bello, 1986; Mangold & Boletzsky, 1987) includes the Sepiolidae of the subfamily Heteroteuthinae, whose members are supposed to be pelagic throughout their life cycle. Mangold Wirz (1963) recognizes in the Mediterranean fauna the unique species Heteroteuthis dispar, the other authors include H. atlantis Voss, which Voss himself (1955) reported at Messina. To this group may now be added Stoloteuthis leucoptera (Verrill, 1878) a species until now recorded in limited Atlantic areas. Verrill (1881) wrote “This species is an exceedingly beautiful one, when living, owing to the elegance and brilliancy of its colours and the gracefulness of its movements. In swimming it moves its fins in a manner analogous to the motion of the wings of a butterfly.”

External ear consists of auricle or pinna and external acoustic meatus. The auricle projects to a variable and individual degree from the side of the head. According to many studies conducted on morphometry of external ear; the size, shape and the orientation of each external ear is unique as ngerprint but it can be generalized. Males have larger ears as compared to females. The present study is attempted provide anthropometric data on normal adult male and female auricles from population of Uttar Pradesh. To st AIM: udy the anthropometric measurements of auricle in population of Uttar Pradesh. MATERIALS AND METHODS: This study was conducted on 420 adults (210 males and 210 females) who were randomly selected from the population of Uttar Pradesh. The parameters measured were, ear length, ear breadth lobule length and lobule width of both ears. RESULTS: In our study, we found that both the ears are equal dimension except for lobule breadth, irrespective of the sex. CONCLUSION: Knowledge of normal ear dimensions is important in the diagnosis of congenital malformations and acquired deformities, and in planning of treatment. The data presented in this study would help the clinician to produce an anatomically correct ear during its reconstruction.

Visual evoked potentials were recorded for 6 adult male subjects in response to single vowels and consonants in printed and script forms. Analysis showed the vowels in the printed form to have evoked responses with shorter latency (component P1 at about 133 msec.) and larger amplitude (component P1-N1) than the other letter-typeface combinations. No hemispheric asymmetries were found. The results partially agree with the behavioral data on the visual information-processing of letters.

Fourty adult male rabbits were used in this study. The animals were randomly divided into four groups,the first group was given distilled water (control) ,while the other third groups were given (2,4,6 µg/kg) of Clenbuterol drug for 30 days. Blood samples were collected after 14 and 30 days of the treatment for biochemical study. Drug caused non significant increase(P

Choral Reading

This study investigated use of choral reading with filtered components of speech and whispered speech on the frequency of stuttering. Three passages read by a normal adult male were lowpass filtered with kneepoint frequencies at 100 Hz (approximate glottal source), 500 Hz (source and first formant), and 1 kHz (source and the first two formants). Along with a whispered passage, a normal passage, and a control condition, these stimuli were used in a repeated-measures design with 12 adult stutterers as they read passages while listening to one of the stimuli. Frequencies of stuttering in each condition were analyzed. The choral speech, the 500-Hz, the 1-kHz, and the whispered speech conditions all decreased the frequency of stuttering while the 100-Hz stimuli did not. It is suggested that articulatory events, chiefly the encoded speech output from the vocal tract, create effective cues and may induce fluent speech in people who stutter.

About 100 µg of copper as cupric acetate-Cu64 was given iv to adult, male rats. Maximal concentrations of Cu64 were reached quickly in the excretory organs—liver, kidney, and gastrointestinal tract—which then slowly released their radioactivity. In most of the other organs a progressive accumulation of Cu64 began after the disappearance of most of the nonceruloplasminic Cu64 from the plasma and after ceruloplasmin-Cu64 emerged in the plasma, suggesting that ceruloplasmin may be the copper donor for the tissues. The disappearance of plasmatic Cu64 tended to parallel that from the liver after the first 48 hr.

87 young adult male students were randomly divided into two groups. One group read an account of a young man interacting with preschool-age children in a nurturing manner. The other group read a nonnurturing account of the same interaction. The subjects rated the nurturing male as higher in goodness and obedience and lower in masculinity, potency, activity, and instrumental achievement potential than the nonnurturing male. From this it was concluded that some men may experience sex-role anxieties when they observe other men behave in a nurturing manner.
