Abstract:
This study aimed to examine effects of adjunctive baicalin therapy to ampicillin for experimental bacterial meningitis in rabbits. After Escherichia Coli inoculation, mean leukocyte counts, concentrations of protein, tumor necrosis factor-alpha (TNF-alpha), interleukin-1 (IL-1) and lactate in cerebrospinal fluid (CSF), brain water content and mean arterial and intracranial pressures substantially increased in the meningitis group. Ampicillin alone for 5 h markedly exacerbated the enhanced leukocyte counts and protein concentration, and showed no significant effect on the elevated CSF TNF-alpha, IL-1 and lactate concentration, mean arterial and intracranial pressures, and brain water content. Baicalin (7-D-glucuronic acid-5,6-dihydroxyflavone, C(21)H(18)O(11)) completely counteracted ampicillin-induced exacerbation, and further alleviated the enhanced mean leukocyte counts and protein concentration when combined with ampicillin. Adjunctive baicalin also significantly ameliorated the elevated CSF TNF-alpha, IL-1 and lactate concentration, mean arterial and intracranial pressures, and brain water content. Baicillin, as an adjunctive treatment exerted multiple therapeutic effects in experimental bacterial meningitis.
Insights
This study found that baicalin, when used with ampicillin, effectively treats experimental bacterial meningitis in rabbits. Adjunctive baicalin therapy significantly reduced inflammation and improved key health indicators in rabbits with meningitis.
Area of Science:
- Neuroscience
- Pharmacology
- Infectious Diseases
Background:
- Bacterial meningitis is a serious infection causing inflammation and increased intracranial pressure.
- Ampicillin is a common antibiotic, but its efficacy in severe meningitis can be limited.
- Baicalin is a flavonoid with known anti-inflammatory properties.
Purpose of the Study:
- To investigate the therapeutic effects of adjunctive baicalin therapy combined with ampicillin for experimental bacterial meningitis.
- To evaluate the impact of this combination on cerebrospinal fluid (CSF) markers, intracranial pressure, and brain water content.
Main Methods:
- Induction of bacterial meningitis in rabbits using Escherichia coli.
- Administration of ampicillin alone or in combination with baicalin.
- Measurement of CSF leukocyte counts, protein, TNF-alpha, IL-1, lactate, brain water content, and arterial/intracranial pressures.
Main Results:
- Ampicillin alone exacerbated certain meningitis markers.
- Adjunctive baicalin counteracted ampicillin-induced exacerbation and alleviated inflammatory markers.
- The combination therapy significantly reduced CSF inflammatory markers, intracranial pressure, and brain water content.
Conclusions:
- Adjunctive baicalin therapy demonstrates significant therapeutic benefits in experimental bacterial meningitis.
- Baicalin enhances the effects of ampicillin, offering a promising treatment strategy.
- This combination therapy presents a multi-faceted approach to managing bacterial meningitis complications.
