Isotretinoin effect on alveolar repair after exodontia-a study in rats.
Summary of "Isotretinoin effect on alveolar repair after exodontia-a study in rats."
To evaluate isotretinoin effect on alveolar repair after tooth extraction of maxillary incisor and serum calcium levels in rats. STUDY
Wistar rats (60-day-old) were assigned to control (CG, n = 12) and experimental (EG, n = 20) groups. EG received daily isotretinoin (7.5 mg/kg) for 30 days before surgery and until euthanasia, 7, 21, 28, or 90 days after tooth extraction. Blood was collected in the EG to analyze serum calcium levels before isotretinoin administration and at euthanasia. Right hemimaxillae underwent histological examination, and the slides were stained with HE and analyzed by descriptive light microscopy.
There was acceleration in the process of alveolar repair in the EG at all time points when compared to controls. Serum calcium levels showed a statistically significant decrease between first and second blood collection at days 21, 28, and 90.
Daily isotretinoin in a dose corresponding to the treatment of cystic acne accelerated alveolar repair.

Aim: The aim of this study was to evaluate the osteoprotective effect of aqueous Rhizoma Dioscoreae extract (RDE) on the alveolar bone of rats with ovariectomy-induced bone loss. Methods: Female Wista...
Angioedema is the swelling of the mucosal membranes as a variant of urticaria induced by hereditary C1 esterase inhibitor enzyme deficiency, certain foods, or drugs. Herein, we report the case of a 23...
Isotretinoin, a known teratogen, is strictly regulated through the iPLEDGE program. However, isotretinoin-exposed pregnancies continue to occur.
Supplemental oxygen treatment in preterm infants may cause bronchopulmonary dysplasia (BPD), which is characterized by alveolar simplification and vascular disorganization. Despite type II alveolar ep...
Isotretinoin is the standard treatment for refractory severe nodulocystic acne. A true association between prior isotretinoin use and development of inflammatory bowel disease (IBD) is uncertain. Addr...

Medical and Biotech [MESH] Definitions
Inbred rats derived from Sprague-Dawley rats and used for the study of salt-dependent hypertension. Salt-sensitive and salt-resistant strains have been selectively bred to show the opposite genetically determined blood pressure responses to excess sodium chloride ingestion.
Factors that modify the effect of the putative causal factor(s) under study.
An outbred strain of rats developed in 1915 by crossing several Wistar Institute white females with a wild gray male. Inbred strains have been derived from this original outbred strain, including Long-Evans cinnamon rats (RATS, INBRED LEC) and Otsuka-Long-Evans-Tokushima Fatty rats (RATS, INBRED OLETF), which are models for Wilson's disease and non-insulin dependent diabetes mellitus, respectively.
The reconstruction of a continuous two-stranded DNA molecule without mismatch from a molecule which contained damaged regions. The major repair mechanisms are excision repair, in which defective regions in one strand are excised and resynthesized using the complementary base pairing information in the intact strand; photoreactivation repair, in which the lethal and mutagenic effects of ultraviolet light are eliminated; and post-replication repair, in which the primary lesions are not repaired, but the gaps in one daughter duplex are filled in by incorporation of portions of the other (undamaged) daughter duplex. Excision repair and post-replication repair are sometimes referred to as "dark repair" because they do not require light.
Mutant strains of rats that produce little or no hair. Several different homozygous recessive mutations can cause hairlessness in rats including rnu/rnu (Rowett nude), fz/fz (fuzzy), shn/shn (shorn), and nznu/nznu (New Zealand nude). Note that while NUDE RATS are often hairless, they are most characteristically athymic.
