Sublingual varicosities and vitamin C in elderly vegetarians
Age and Ageing
|February 1, 1977
Summary
Long-term vegetarian diets rich in vitamin C (ascorbic acid) correlated with fewer tongue lesions in the elderly. This suggests sustained high vitamin status may prevent irreversible age-related changes, unlike later vitamin therapy.
Area of Science:
- Nutrition Science
- Gerontology
- Vascular Health
Background:
- Elderly populations often exhibit increased incidence of sublingual petechiae and varicosities.
- Vitamin status can decline with age, potentially impacting tissue health.
- Previous research suggests a link between vitamin deficiencies and age-related physiological changes.
Purpose of the Study:
- To investigate the association between long-term high vitamin C status and the prevalence of specific tongue lesions in elderly individuals.
- To explore the potential for irreversible age-related changes due to past vitamin deficiencies.
- To compare the informativeness of epidemiological studies versus therapeutic trials for understanding vitamin effects.
Main Methods:
- Study involved 22 elderly individuals with a long history of vegetarianism.
- Assessed plasma and leukocyte ascorbic acid levels.
- Conducted visual and photographic examinations of the tongue for petechiae and varicosities.
Main Results:
- Participants exhibited high ascorbic acid levels in plasma and leukocytes.
- A lower incidence of sublingual petechiae and varicosities was observed compared to the general elderly population.
- These findings suggest a protective effect of sustained high vitamin C status.
Conclusions:
- Long-term, high vitamin C status may play a role in preventing or reducing the severity of certain age-related oral vascular changes.
- Irreversible changes may occur in the elderly due to past vitamin deficiencies, limiting the efficacy of subsequent vitamin therapy.
- Epidemiological comparisons of populations with stable vs. variable vitamin status may offer greater insight than vitamin intervention trials for these specific lesions.

01:22Connective Tissue Cell Types
Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

01:18Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants
Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

01:30Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
01:26Varicose Veins I: Introduction
Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...
01:26Varicose Veins II: Diagnostic Studies and Interprofessional Care
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
