Observations on the effects of formaldehyde on cockroaches and their flora: II. Prolonged survival of cockroaches drinking formaldehyde or glutaraldehyde solutions.

Adult cockroaches were found to survive up to 22 weeks when provided with 1% Formalin (0.4% formaldehyde) in lieu of drinking water. Given 4% Formalin or 2% glutaraldehyde they survived up to 41 days. During the experiments eggs were laid and hatched and the offspring continued to grow. Combined with surface disinfection, this may hold out a simple method of rendering adult cockroaches gnotobiotic or even axenic.

Observations of the effects of formaldehyde on cockroaches and their flora: III. The effect of formaldehyde in eliminating the normal gut flora.

The normal flora of cockroaches (Periplaneta americana) was determined over a period of 24 days prior to substituting water with 1% Formalin for drinking water. During the first 4 days of treatment the normal flora was significantly reduced and by the fifth day, when the cockroaches became diarrhoeic, no bacteria, fungi, or viruses could be detected by the methods used.

Surgical treatment of submucosal tumors of the hard palate.

Two cases have been presented to illustrated to illustrate the principles of total excisional biopsy for palatal tumors and the postoperative management of the resulting defect with the use of palatal splints. Total excisional biopsy is curative for benign tumors and for some malignant-grade tumors, and is the preferred method of treatment when possible. Total excision of the lesion with adequate margins negates the possibility of seeding the tumor into surrounding tissue or of leaving behind residual tumor.

The role of antisense oligonucleotides in the wave of genomic information.

Technologies which efficiently dissect gene function and validate therapeutic targets are of great value in the post-sequencing era of the human genome project. The antisense oligonucleotide approach can directly use genomic sequence information, in a relatively time and cost effective manner, to define a gene's function and/or validate it as a potential therapeutic target. Antisense oligonucleotide inhibitors of gene expression may be applied to cellular assays (in vitro) or animal models of disease (in vivo). Information generated by this approach may then direct or supplement traditional drug discovery programs, or support development of the antisense oligonucleotide inhibitor, used to validate the target, as a drug.
