Antihistamine-related deaths in England: Are the high safety profiles of antihistamines leading to their unsafe use?

Aims: Antihistamines are routinely taken to control allergic reactions or sedation to induce sleep. There are, however, growing concerns regarding sedating antihistamine misuse. This research aims to evaluate deaths related to antihistamines in England occurring during 2000-2019.

First Report of Soybean Rust (Phakopsora pachyrhizi) in Nigeria.

Rust caused by Phakopsora pachyrhizi H. & P. Sydow was observed for the first time on soybean (Glycine max [L.

Lymphocyte transformation suppression caused by pyoderma--failure to demonstrate it in uncomplicated demodectic mange.

Three dogs with demodectic mange uncomplicated by a bacterial infection and 9 dogs with demodectic mange and pyoderma were tested for their lymphocyte response to phytomitogens in vitro and for the presence of the serum's lymphocyte immunoregulatory factors (SLIF) suppressing blastogenesis. None of the 3 dogs with uncomplicated demodectic mange showed any detectable dysfunction of their lymphocytes or presence of the blastogenesis suppressing SLIF. Their lymphocytes generally responded to the mitogens with more blastogenesis than lymphocytes from healthy controls.

Effect of serum on lymphocyte blastogenesis. I. Basic characteristics of action by diseased dog serum.

The immunoregulatory effect of serum on phytomitogen-induced lymphocyte blastogenesis was studied in 4 sera from diseased dogs and 1 serum from a clinically healthy dog. The results indicated that: (1) Each of the diseased animals responded to the given infection with a specific pattern of blastogenesis inhibition. (2) The blastogenesis suppression in vitro was proportional to the content of the suppressive serum in the medium.

Feline (cat) hemolytic complement optimal testing conditions.

Optimal conditions for assaying feline (cat) hemolytic complement (C) were determined. Effects of the following factors on C titers were tested: pH, ionic strength; calcium, magnesium, and ethylenediamine tetraacetate concentrations; time and temperature of incubation. Guinea pig erythrocytes sensitized with feline antibody were the most sensitive target cells for feline C.
