Objective: In recent years, antibiotics have been used widely in the glob to prevent and treat bacterial diseases. They injected into eggs to eliminate pathogens and prevention of egg transmission of disease, but the adverse effects of drugs have always been a major concern. There is little information available about the safety of tetracycline drugs in the embryonated eggs of the birds. The ob...

Infectious agents cause disease in virtually any susceptible hosts. In the poultry production and medicine, pathogens were eliminated from a line of a breeder by injection of antibiotics into hatching eggs. There is little information available describing the safety of the folate antimetabolite/sulfonamide class of antibiotics on the game birds embryonated eggs. The objective of this study was ...

The multiplication of Rickettsia mooseri in fertile eggs is speeded up and quantitatively increased by single dose x-radiation given either 24 hours before or 48 hours after inoculation. This effect is noted at all dosage levels studied, ranging from 100 to 1500 r. The rickettsiostatic effects of high incubation temperature (40 degrees C.) and of streptomycin are neutralized by radiation, but t...

Poor sperm motility is an important factor in male infertility. Preliminary results in our laboratory on a group of 19 men (10 suspected infertile men and 9 fertile donors) showed stimulation of sperm fertilizing ability after sperm washing with theophylline as demonstrated by zona free hamster egg penetration test. The egg penetration rate for the control spermatozoa samples from subfertile me...

In 1936 Bittner demonstrated for the first time that mammary cancer in the laboratory mouse is related in some way to a substance found in the milk. So-called low-tumor strains could be made to develop cancer by feeding the young mice with milk derived from a high-tumor strain mother, whereas the incidence of mammary cancer in high-tumor strain females could be greatly reduced by foster nursing...

Specimens of urethal discharge and scrapings of the urethra from 45 men with non-gonococcal urethritis have been studied for virus content. Human amnion and monkey kidney cell cultures were inoculated. Various temperatures of incubation were used. Specimens were also inoculated into the yolk sac of seven-day fertile eggs. No cytopathic changes were detected in any specimen examined after direct...

Objective: Fungal agents cause disease in virtually any susceptible hosts. In the poultry production and medicine, pathogens were eliminated from a line of a breeder by injection of antifungals into hatching eggs. There is little information available describing the safety of the antifungal drugs on the birds embryonated eggs. The objective of this study was to investigate the efficiency of the...

Objective: In recent years, antiviral drugs have been used widely in the glob to prevent and treat viral diseases. They injected into eggs to eliminate pathogens and prevent of egg transmission of disease, but the adverse effects of drugs have always been a major concern. There is little information available about the safety of antiviral drugs in the embryonated eggs of birds. The objective of...

Objective: In recent years, amino acids are used in veterinary medicine for many purposes. They injected into hatching eggs to increase chick body weight and performance at hatch, but the adverse effects of amino acids have always been a major concern. There is scant information available about the pathological alterations of amino acids in the chicken embryonated eggs. The objective of this st...
