On 25th November, 1939, one Dr. A received an injection of anti-tetanic serum 500 units, for a shoe-nail bite on his heel. Almost at once he developed the following symptoms and signs:? (1) Symptoms.?Severe constricting pain across the chest, inability to breathe properly and giddiness. _ (2) Signs.?Cyanosis of the face, urticarial eruptions all over the body and weak pulse leading to a complet...

Various authors have reported 24 hr. cycles of activity in Aedes aegypti (L.); these reports include the field observations of Boorman (1961) on biting and McClelland (i960) on biting and flight, and the laboratory studies of Haddow & Gillett (1957) on oviposition and Gillett, Haddow & Corbet (1962) on sugar-feeding. As a result of their laboratory studies, Gillett, Haddow & Corbet (1959, 1962)...

Mandibular single denture opposed by maxillary natural dentition showed a great problem. However, mandibular implant overdenture treatment has gained considerable recognition. Ten male patients with complete mandibular edentulous arch and opposing arch have full natural dentition. Patients were divided into two groups. All patients received two endosseous titanium implants. In Group I, patients...

In male Long-Evans hooded rats, we examined: (1) combined effects of neonatal anoxia and novelty exposure on aggression during adulthood; (2) open-field activity before juvenility as a predictor for adult aggression. Litters of neonates were exposed to either 100% N2 gas (Anoxia) or room air (Control) for 25 min on postnatal Day 1 (P1). Within each of the Anoxia and Control conditions, one half...

Trellis linearity, rst considered by McEliece in 1996, turns out to be crucial in the study of tail-biting trellises. In this chapter, basic structural properties of linear trellises are investigated. A rigorous deeni-tion of linearity is given for both conventional and tail-biting trellises. An algorithm that determines in polynomial time whether a given trellis is linear is then derived. The ...

We investigated whether the descending noradrenergic system regulates allergic itch. Mosquito allergy of the hind paw elicited biting, an itch-related response, in sensitized mice. The biting was inhibited by intrathecal clonidine and reversed by yohimbine, an α(2)-adrenoceptor antagonist. The biting was increased by intrathecal pretreatment with the catecholaminergic neurotoxin 6-hydroxydopami...

Swarm-founding wasp workers (genus Polybia) exhibit developmental changes in task specialization known as temporal polyethism. Young workers typically remain inside the nest, followed by a period of working on the exterior nest surface, and later by foraging. Polybia workers on the nest exterior engage in biting interactions with their nest mates, and workers that are bitten are more likely to ...
