Abstract
Cell wall fractions of Micropolyspora faeni, a causative agent of hypersensitivity pneumonitis, have been shown to possess non-specific mitogenic activity for guinea pig, rabbit and human lymphocytes. This activity was unrelated to endotoxin and may not be associated with peptidoglycan. This lymphocyte proliferation stimulus may play a role in the adjuvant properties of this organism and in the etiology of hypersensitivity lung disease.

Abstract
There have been few assessments of residency programs by graduates; therefore, to investigate a practical means of evaluating programs we asked former trainees to relate aspects of their training to present professional needs. Former residents in the Duke pediatric program from 1960 to 1972 were asked to evaluate various aspects of their training. The overall training program was rated favorably, as were most deficiencies were identified in ambulatory pediatric care, such as surgery, dermatology, psychiatry, and radiology. Analysis according to respondent's period of participation in the program and current professional activity revealed little variation in patterns of response. This survey method provides an inexpensive means of monitoring inadequacies in residency programs and provides data to initiate changes.

Abstract
Romanomermis Coman, 1961 is resurrected from the synonymy of Eurymermis Müller, 1931, the generic description is augmented, and three new species are described: Romanomermis kiktoreak, R. hermaphrodita, and R. culicivorax. R. culicivorax is a segregate of a complex known previously as Reesimermis nielseni Tsai and Grundmann, 1969. R. nielseni is restricted to a species known only from Wyoming. Reesimermis Tsai and Grundmann is suppressed and R. nielseni s.str. is transferred to Romanomermis. Reesimermis muspratti Obiamiwe and Macdonald is moved to Octomyomermis Johnson. Keys are provided for the world species of Romanomermis and for the described mermithids that infect mosquitoes in North America. A brief commentary is included on the taxonomic utility of length and degree of fusion of the spicules, body shape, cuticular fibres, and double molt to adult.

Abstract
A multi-centre open study in general practice was carried out to assess the efficacy of and incidence of side-effects with the tricyclic antidepressant, butriptyline. Of a series of 153 patients with non-psychotic depression, with or without anxiety, 105 (69%) were judged as having a good or fair response to treatment with 75 mg to 150 mg butriptyline daily. Side-effects of an anticholinergic nature were seen in 13.7% of patients, but the incidence decreased to less than 4% in the 101 patients receiving treatment for over 7 weeks.

Abstract
The self-reported child-rearing practices of 214 parents of battered babies were characterized in a few but not all respects by demanding behaviour which exceeded that to be expected in relation to their social class and age. Inconsistency in child management was noted in the comparison between lack of demonstrativeness and emotional over-involvement, and between physical punishment and a tendency to be lax in the supervision of the child, and was reminiscent of parents of delinquents. Unhappiness and hostility in relationships with members of their families of origin, with unsupporting partners and with people in general were other important features. Generally, identified perpetrators were characterized by features significant for the sample as a whole.

Abstract
Several investigators have reported lipid A as the biologically active unit in the lipopolysaccharide (LPS) molecule. To determine if lipid A was responsible for the reported increases in pyruvate kinase, mice were injected with endotoxin from Salmonella typhimurium SR-11, the Re mutant of Salmonella minnesota R 595, and lipid A-bovine serum albumin conjugate. The livers were homogenized and the activity of pyruvate kinase was measured. Similar increases in enzyme were obtained with all three preparations. These data imply that the lipid portion of the LPS molecule was responsible for alterations in host enzyme activity. To further determine if the lipid portion was the active unit, a lipid-degraded endotoxin (endotoxoid) prepared by potassium methylate treatment was inoculated into mice. An initial increase in liver pyruvate kinase activity was observed with all preparations. The marked increase observed at 16 h with the native product and lipid A conjugate was not obtained with the endotoxoid. These experiments extend and confirm previous observations that lipid A is responsible for the effects associated with LPS. Animals tolerant to endotoxin from S. typhimurium SR-11 were challenged with endotoxin from the Re mutant. A significant increase in pyruvate kinase activity was not obtained, suggesting that anti-O antibodies are not important in the development of tolerance.

Abstract
Changes in non-specific esterases of Aedes aegypti were noted during pupal development. One esterase band was found to increase markedly within 3 h of pupation and this increase in activity was suppressed by prior treatment of larvae with an insect growth regulator, ZR 515. It is suggested that the esterase activity may help to reduce endogenous levels of juvenile hormone during metamorphosis and that the growth regulator may prevent this normal regulation.

Abstract
Inexperienced hand-reared motmots avoided a pattern of red and yellow rings but readily attacked a pattern of green and blue rings and also one of red and yellow stripes. The motmots' avoidance of the "coral snake%" pattern indicates that mimic snake species can derive protection from some potential predators.

Abstract
In spite of increasing interest, the problem of the battered child remains controversial. Some see the problem as a response to stressful social circumstances and society's permissive attitude to violence (23), others view it as primarily a manifestation of parental maladjustment (64).

Abstract
A controlled investigation of 134 battered children showed that nearly half had serious injuries and 21 died. Sixty-five had been battered more than once, 20 had permanent neurological sequelae, a quarter were low birth weight babies, and 10 had serious congenital defects. Twenty-three had been previously admitted to hospital with failure to thrive and the overlap with physical neglect was considerable. Mortality and morbidity among their siblings was also high. Difficulties with the child were attributable to interaction with neurotic mothers.The risk of battering diminishes after a child's second birthday. The establishment of specialized hospital teams to tackle the overall problem is suggested as a method of improving management. Prevention may lie in educating mothers in the basic physical and psychological requirements of children and overcoming their reluctance to avail themselves of medical care.

Abstract
Ketamine hydrochloride alone was an effective analgesic in the Mongolian gerbil. In 28 young adult animals of both sexes (bodyweight 45-68 g) intramuscular injection of 44 mg/kg produced analgesia in about 83 seconds. Deep surgical anaesthesia could be readily achieved in about 12 min from start when methoxyflurane was administered by nasal cone 5 min after ketamine injection, and the surgical level was maintained arbitrarily for about 40 min during part of which laparotomy was performed. Induction of deep anaesthesia was smooth and recovery occurred uneventfully. The combination of ketamine and methoxyflurane allowed effective control of both the depth and duration of anaesthesia. Recovery time was about 77 min. Sex differences generally were slight.

Abstract
A controlled investigation of 214 parents of battered babies shows that they were young and predominantly of lower social class. Premature parenthood is an associated feature. Among the mothers 76% had an abnormal personality and 48% were neurotic. Nearly half were of borderline or subnormal intelligence; 11% had a criminal record. Of the fathers 64% had an abnormal personality, more than half being psychopaths. Twenty-nine per cent. had a criminal record. Recidivism is an associated feature.The risk of battering possibly diminishes with time. The teaching of appropriate child-rearing skills, symptomatic relief, and social relearning are suggested as realistically based treatment methods and should be combined with a care order. When response to treatment appears unlikely permanent removal from parental care should be considered.

Abstract
Out of 35 parents who battered their children eight had an abnormal E.E.G. All of these were found to be psychopathic, of low intelligence, and to be persistent batterers. The presence of an abnormal E.E.G. strongly suggests that some baby batterers are more closely related to those who commit acts of violence and that taken as a whole they are not a homogenous group about whom it is safe to generalize. The possibility of a separate subgroup among baby batterers, therefore, needs close attention.

Abstract
Nine poppy-head addicts were seen at a Birmingham hospital. Seven were Sikhs born in Jullundur and two were West Pakistanis. Most began their poppy-head addiction in their early 20s, usually out of curiosity or to relieve the hangover effects of alcohol. Only two took opium in addition and one of these had taken cannabis, morphine, and heroin. They all drank several pints of beer a day and were heavy smokers. All had had little schooling and married young. Most of them were industrious foundry workers in good physical health. Withdrawal of poppy capsules failed in each case. The present situation whereby an addictive drug is readily imported and sold in local shops is questioned.

Abstract
Some aspects of overwintering and oogenesis in the pitcher-plant mosquito, Wyeomyia smithii (Coq.), were examined. The species was shown to overwinter in a diapause state as a third-instar larva. The diapausing larvae overwinter within the frozen ice cores of the host plant but they were nevertheless shown to be intolerant of prolonged periods of freezing at temperatures only a few degrees below 0 °C. The winter survival of the species probably depends almost entirely on the insulating benefits of a snow cover. Larval diapause was stable under short-day conditions but was very rapidly broken when the larvae were exposed to long-day photoperiods. The critical photoperiod required to break larval diapause in a population from the Kenora region of Ontario was between [Formula: see text] and 15 h of light per diem. This critical photoperiod did not change during a prolonged period of overwintering. Larvae which experienced 5 or fewer long-day cycles remained in diapause when they were returned to short-day conditions but diapause was irreversibly broken in larvae exposed to 8 or more long-day cycles in succession. Data on growth rates of larvae as a function of temperature and photoperiod were used to predict the seasonal cycle of W. smithii in northwestern Ontario where the species is probably restricted to a maximum of two generations per year. All females of W. smithii were autogenous for the first ovarian cycle and adult diets of carbohydrate did not affect fecundity. Unlike other mosquitoes, the female of W. smithii was found to be precocious, emerging with the ovarian follicles already initiated with development of the follicles up to stage IIIa of Christophers.
